@Bald new you pretty much get what you pay for - want better than 1050ti you'll need to pay for better than 1050ti. A used GTX 970 should be similar in cost but a lot faster. Slightly more for a GTX 980.
+LinusTechTips Btw Linus, what do you think about a video comparing nvidia Shield streaming to the Moonlight stream app on a random tablet/phone that is compatible with nvidia gamestream?
I'd love to get some 10 gigabit between my PC and NAS, but I'd need to upgrade the card in the NAS, my switch, the cabling, and the NIC in my PC - so essentially every piece of hardware involved :P lol
Not sure how people watch this video and come to the conclusion that they have a 10Gbps link to their ISP. The 10Gbps speeds are just for their internal network. Their "Internet" speed I imagine is just standard business fibre at 1Gbps
Casey Stellar Well yeah it depends where your business is located but business's get the option of paying outright to get a leased connection installed, even if it is ridiculously expensive.
I'm surprised that the video is again washed out :/ You guys have a problem with a monitor calibration or someone doesn't know what they're doing... It doesn't destroy the video, but it's not very pleasing to watch :( Edit: Mistakes happen, that's normal, but I would hope you guys get it under control soon.
it's not that it's washed out, it's confirming video levels for the web.. the have color calibrated monitors and use certain colors so that it's easier to distinguish whites and Black's and details in the shadows and highlights are preserved.. otherwise you lose data in the video and lose video quality as well
+jack black It's actually a lack of contrast. Most people set up their cameras to shoot as much latitude as possible to give more headroom in color correction. This has probably just been rushed out. Skin tones look a little weird, probably down to LED lighting which can ave a really poor CRI. Tbh, it's not worth complaining about, but the tech world is filled with pedants.
I've been really waiting for some coverage on this topic. I picked up a couple SFP+ cards and a cable to run between my 2 main studio rigs and am setting up a 10gbe connection between them, but I've yet to find an "affordable" 10gb switch for my budget, haha.
Have you tried disabling UDP/TCP offload and Large Send Offload for IPv4 and IPv6? I know I've had similar problems with Hyper-V where TCP/UDP offload severely throttles network speeds because it's offloading work to the CPU.
the people who visit this channel are already kinda into tech stuff, and yet so many of them don't even know what this video is talking about and start comparing their internet speeds to this, makes one wonder what knowledge the general public has on these kind of stuff.
First, this is NOT an attack on your comment. It always amazes me also at what some people are totally oblivious to. Not everyone who watches this channel has a computer tech ability at all. Many watch this channel to try to learn about specific technologies to increase their knowledge. So yeah, the general public may be into using computers, but many have no working concept of how or why they work. Many people do not even understand the differences between RAM and what a Hard Drive is. It is all storage in many people's minds. Add SSD, which really is memory, and you have completely lost them. Forget about even more basic concepts like BIOS and what ROMs are. It comes down to what a person really wants to do with a computer. If they have no interest in programming, they typically will never learn basic programming concepts. If they have no interest in how the computer works inside, they often will never learn what the basic components and terms are. If you just drive a car for transportation, you may not know what size your engine is, how many cylinders it has, or even what type, or where the oil goes! It is human nature to not be concerned about what does not matter to you. Who knows what they ate for breakfast 2 weeks ago? Who knows their cholesterol levels? Who knows their blood type? How about all the birth dates of everyone in the family? These are all basic points of information, but unless a person actually cares about them, it is unlikely they will know the answers. Years ago, the government was horrified at the revelation that people were so illiterate, that many did not know how to even set the clock on their VCRs! It gets very old to set a clock all the time, you do not need, since you may never use the VCR for timer recording. Especially when power bumps occur and it has to be done again EVERY time! People did not know how to set the time, because it did not matter to them. Many people are the same with Microwave Ovens today! At the same time, many of these people have amazing skills at things I would never want to know, such as being medical physicians and molecular biologists (I think there is such a field right?), and even more basic needed skills such as physical strength and endurance to build and maintain our roads and freeways! We are all different, and the best goal is to help each other as needed, and be willing to also accept help from others. We can all learn, and we can all teach. It just depends on what the topic is at the time.
why is everyone going on about internet speeds? he is mainly using it for LAN. So production guys can transfer/work with large files from the fileserver.
holy christ. Network speed =/= internet speed. Network speed is the data rate between their in house servers and computers, i.e. moving videos from one machine to another. Internet speed is what you use for downloading crap off the internet.
+Xuvial Sylvester I like the vessel app more than the new UA-cam layout, considering that it is a band new service it will only get better with time. also no need to deal with Google bullshit
FYI: Jumbo Frames is a horrible creation. It scales very poorly, especially with respect to switch resource usage, and it gives you no benefit when you are transferring small files. Naturally the overhead is multiplied greatly whenever packet loss occurs congesting what is already an unstable link even further. In theory the maximum difference in performance on a 10Gb link with or without Jumbo Frames for large payloads would be in the area of 5-6% meaning that the maximum benefit they should give you is 75 MB/s faster transfer. While that is a noticeable difference it does not explain what you are seeing. I would wager that the other changes you made to the NIC, number of CPU threads and to a lesser degree the send buffers, had a much larger impact.
Linus, I'm gonna go out on a limb here. Maybe the machines that you were experiencing slower transfer speeds had a cable length/distance of greater than 100m? Limitations of CAT6A/7 with 10GBaseT.
Does this switch have shared or dedicated port buffers? And it's probably not non-blocking ( overbooked backplane ). Also watch out with jumbo frames. It can improve throughput, but I have seen very wierd cases with iscsi and nfs where packets were dropped because of unexpected packet sizes. In your case with native SMB3 please check the tcp window frame sizing. You can tune your nics with netsh.
People in the comments need to understand this isn't internet speeds. It's their internal network from their group of computers. Basically used for fast file transfer throughout the office.
I mean 1GB/s in general would be freaking awesome no doubt, but the ~500MB/s you get sometimes are quite good as well. I can't really remember when I did such big transfers that often. Ok, sometimes I copy films on my Home-Streaming PC and my network is running on about 300MB/s, It usually doesn't take longer than 10 minutes, which I think is quite OK. Especially when I do that 3 to 6 times a year. And yeah, I get that your channel is all about CRAZY STUFF haha :D, but as I said in general I would be happy with ~500MB/s.
I do have 20 symetric :p but this video is about 10 gbits speed in their own networking (just betwen the computers at their office) not their internet speed (ips) also to mention not to confuse gbits with gbytes
I'm watching this video with an ADSL in Italy. Yeah, an ADSL. With about 500 KB/s download, 200 KB/s upload and 30 ping. Thanks Linus, now I'm going to kill myself.
The issue may be your MTU sizes (aka Jumbo Packet size), you mention "it doesn't seem to matter if your values don't match up exactly", this isn't entirely true, what you are doing is causing an MTU mismatch between your machines, this will cause lots of weird issues because you're dropping packets. If you have one machine's MTU set higher than the other's then you'll have the exact symptoms you are describing. Try setting all of your MTUs or Jumbo Packets to the same size.
So lets see, the comments thus far, the video is washed out, this is something that people care about obviously because they incessantly go on about it. The next group can't comprehend the content so they ramble on about what they think it's about then another group has to explain to them what the actual content is about. Then you have the trolls who have such crappy lives they literally post stupidity where ever they can so they can show the world what an idiot looks like. I don't know how Linus does this for a living, the idjits out number the people you want watching your channel it seems. My take on this video, it was well done as always, I could care less if it's washed out a bit, the channel and equipment are a work in progress. I don't watch Linus for perfectly done videos, I watch for the content. As for 10 gigabit, I'm hoping to make the move so at least my server and my main workstation have 10 gigabit connectivity and I hope to attain at least 500 megabyte transfers. I've been happy with 110 to 129 megabyte sustained transfers (the max Gigabit can hit) but ever since the move to NVMe and SSD's in the server, I need the speed!
+KlipschHead281 The only things these problems prove is Linus is getting popular. Who knows, he may advance to the point of disabling UA-cam comments altogether
10Gbps networking has been in my roadmap for a year now. It sucks having to wait 3 hours for a file to transfer at 1Gbps speeds. I prewired with cat6A when I was doing the runs to my server.
Nice. I was so worried about my old cat5e network when i got my 300mbit internet but it could handle it. Even tho most of the internet is lagging behind (pretty much only steam can do those speeds) its clear that you shouldnt invest in less than cat6. These very high speeds also question if you really need large local space as you can pull data so fast from afar that itll feel like its "local on a old hdd" or similar.
the said ssd should be as fast as ram or faster for it to be used efficently as cache which in this case is pretty much useless since ram for storage is already faster than any known type of storage
Maybe using a Linux or BSD would work better? I would never trust Windows for performance... (Also, I am aware that there are others, but those are the ones I know that are best for networking)
For those who won't need RJ45-specific cabling, then I just picked up an Emulex P004096-01K network card with 2x SFP+'s for $50, and a 48-slot Quanta LB4M switch with 2x SFP+ uplinks for $95 That's $145 in ebay money (excl. ship n tax) for a cheapo 10Gbit setup.
Dunno whether someone has mentioned it, but if the MTU on both ends doesn't match, you'll end up bottlenecking at the switch, cause it would need to repackage every single freakin frame (I've run into this multiple times with corporate clients). Also the first thing you do whenever you get above 1GbE is to setup jumbos and increase the Rx and Tx buffers. TOE also helps. The faster/slower transfer inconsistency with spindle drives is usually due to the block sizes discrepancies or lack of fine tuning (depending on the majority of files being stored it makes a HUGE difference whether you're running with 4K or 512K blocks), but since you're using SSDs and RAM disk, I honestly have no idea what might be the reason there.. Also if you're using Windows all across your infra and have enough ports, given the fact you have dualport cards and especially since they're 10X (meaning rj45), I would consider LACP or some sort of balancing trunking - LACP would be best for Win8+ and WS2012r2+ (completely new network stack on both). I could get into more detail if you're interested why LACP and so on, but I guess that's enough for now. Cheers!
10Gb networking really is quite tricky to get right. You are on the right path with the receive side scaling (if you do not use that, all networking is done on core 0, which coincidentally is also the one used mainly for the OS itself, and even with the latest CPU, you won't get more than about 4Gb/s out of one core alone). Since you are using a 2 port card - have you made sure that the receive queues do not use an overlapping CPU core set? You can set a max processor / base processor number for each NIC, try using something like 2 to 8 for one NIC and 10 to 16 for the other for a first test and 4 receive queues for each (only even numbers=physical cores count). With Intel drivers, you should also be OK using all the offloading features. If you are using jumbo frames, make sure they are active everywhere (even your NAS). Also make sure flow control is active on the cards and on the switch ports, it helps a bit. Does your NAS support SMB3 if you're using Win10 / Server 2012R2 clients? With the exact same card you are using, I am getting live migrations with 2x9.8Gb/s utilization between Hyper-V hosts (SMB3 multichannel over two ports in different VLANs), so it is definitely possible :-)
Me and my friend were amazed in 1994 November when we both got 28.8 modems. He came from a 14.4 and me a 2400. We were so excited to see the numbers spin on a file transfer. Then we found IceZmodeM and you could type to each other during file transfers!! TYPE. TO. EACH. OTHER!...So amazing.
It's more likely because you always have a certain overhead on any network. So you would never ever get 100% theoretical value. Hence why 80% better reflect what you can expect in real life
We have had 10 gig for years @ work, using sfp+ and om2 multimode fiber. If we are transferring lots of tiny files, the performance is never very good, single giant files are always fast. I'd check your server to see if any kind of read-ahead and write-back are enabled on the array. Stripe size of the raid(s) can also make a huge difference when writing. For giant files like you describe, I usually make an array w/512K stripes. The higher stripe size always seems to affect write speed, not so much read. I took a local ssd array and changed it from 64 to 512 and got 1600 - >2200 MB/'s difference on writes. Anyway, good luck on your 10gig network!
Linus, do you think that the length of the cable run from your test bench to the server/switch room had something to do with the variable speeds? Have you tried it right beside the switch? Maybe the quality of the connectors used in the network installation might contribute.
The one thing I can think about with having this much speed is virtualization especially if you want to stream enterprise apps to all of your users as well as doing a NAS setup.
Two questions: #1 "More higher", can you really say that?? And #2 A single SSD may be limited to the 600MBps limite but what if you are running RAID?? Genuinely curious...
You guys should do more networking videos. I think you guys are very entertaining and believe you could bring some humor to the subject that could make it less painful.
I have always been told that networks at that speed can not be actually handled due to the length of the able, if you ping one PC to the other you will get
10 gbit networking comes pretty close to uncompressed video and audio transfer over long distances. Imagine gaming on a computer miles away at the exact same speed as if you were sitting in front of it
7:40 WIndows does not have very stable networking, I recommend using linux (specifically a server distro, since they're designed to support crazy networking shit like InfinityBand [400Gbps])
I don't know the details of the server hardware configuration, but if my understanding is correct he's running FreeNAS, whith ZFS, on a hardware RAID array. That may be adding some IO delay. Enabling jumbo frames on the network would be the first step as he did, but I don't think the bottleneck was ever on the network because with wire speed switching you should have no trouble achieving max throughput.
oh yeah if your frame/MTU sizes are different, the individual frames will get broken up along the way and have to be reassembled, this will add tremendous overhead and in that case the bottle neck would be the network.
Your SSD SAN is likely the bottle neck. We have EqualLogic SAN's at work (over $500K a pop) that easily do 10Gbit/sec from one server to another using 10Gbit NICs. Of course we are using Dell's N4000 series 10Gbe L3 switches. Our SAN space is over to a pedabyte.
Linus, there are HUGE performance differences between software RAMdisk solutions; please investigate that further, the free tool shipped with my mobo (asrock's AXTU with xFast RAMdrive) is the best I've tried out of 4. 4k writes differ over 500% between the lot.
@LinusTechTips Make sure both the PC & server is set to high performance mode. I'm not 100% sure if you can tweak the SMB buffers on windows, but for my FreeNAS based server with bonded 10Ge, I needed to raise the SMB buffers significantly before I got good throughput. Also, do note that because SMB is single threaded it has interesting behavior to say the least. You'll notice that if you have a client doing multiple transfers at once, you'll be limited to the slowest connection. So let's say you have a theoretical 700MB/s limit, but for some reason one transfer is going at 100MB/s, the other transfer will be capped at 100MB/s on the windows client. If the slowest transfer goes up, as does the other one. Once that was done, and the client machines weren't in low power states, I was capable of pushing 700-800MB/s on spinning disks from our ZFS servers.

Oh, one more thing. The XS712T has a bug on the new firmware when you run LACP on the SFP+ ports. Sometimes the balancing algorithm will decide to spew lots of heartbeat frames and essentially bottleneck the connection. I haven't seen this happen on the copper ports, but who knows. The latest firmware also quiets down the fans too :D

This isn't internet ISP speeds, this is internal network transfer speeds over LAN.
+Random_Red 100Mb/s internet...
Watching Linus run with the tub of cables. 🤣😂🤣
I'm watching this video with an ADSL in Italy. Yeah, an ADSL. With about 500 KB/s download, 200 KB/s upload and 30 ping.
Thanks Linus, now I'm going to kill myself.
Great tips! Helped increase my 10Gbit speeds from 360MB/sec to 1.1GB/Sec. Keep it coming!
Its my bday, can I be on top?
+RunHao Lin I don't know what would be more surprising. Your comment ? Or if that's exactly what he/she wanted ?
Why do you not try Linux on this setup?
(Because he doesn't know anything about computers, as evident from this video, and the channel is a commercial.)
GOTTA GO FAST
UR 2 SLO!
The issue may be your MTU sizes (aka Jumbo Packet size), you mention "it doesn't seem to matter if your values don't match up exactly", this isn't entirely true, what you are doing is causing an MTU mismatch between your machines, this will cause lots of weird issues because you're dropping packets. If you have one machine's MTU set higher than the other's then you'll have the exact symptoms you are describing. Try setting all of your MTUs or Jumbo Packets to the same size.
2:56 Isn't that Doc's drawing of the "Flux Capacitor" in Back to the Future ?
"They are both somewhat affordable" 300$ - Damn it linus!
So lets see, the comments thus far, the video is washed out, this is something that people care about obviously because they incessantly go on about it. The next group can't comprehend the content so they ramble on about what they think it's about then another group has to explain to them what the actual content is about. Then you have the trolls who have such crappy lives they literally post stupidity where ever they can so they can show the world what an idiot looks like. I don't know how Linus does this for a living, the idjits out number the people you want watching your channel it seems.
My take on this video, it was well done as always, I could care less if it's washed out a bit, the channel and equipment are a work in progress. I don't watch Linus for perfectly done videos, I watch for the content. As for 10 gigabit, I'm hoping to make the move so at least my server and my main workstation have 10 gigabit connectivity and I hope to attain at least 500 megabyte transfers. I've been happy with 110 to 129 megabyte sustained transfers (the max Gigabit can hit) but ever since the move to NVMe and SSD's in the server, I need the speed!
+KlipschHead281 The only things these problems prove is Linus is getting popular. Who knows, he may advance to the point of disabling UA-cam comments altogether
Ahem .. cough pewdiepie cough
MarioDragon I doubt anybody gets that far. :)
+KlipschHead281 A few of the top guys have...
MarioDragon Kudos to them, damn...
10Gbps networking has been in my roadmap for a year now. It sucks having to wait 3 hours for a file to transfer at 1Gbps speeds. I prewired with cat6A when I was doing the runs to my server.
Nice. I was so worried about my old cat5e network when i got my 300mbit internet but it could handle it. Even tho most of the internet is lagging behind (pretty much only steam can do those speeds) its clear that you shouldnt invest in less than cat6. These very high speeds also question if you really need large local space as you can pull data so fast from afar that itll feel like its "local on a old hdd" or similar.
imagine an ssd with a 1 tb cache
so... an ssd with another ssd as cache?
the said ssd should be as fast as ram or faster for it to be used efficently as cache which in this case is pretty much useless since ram for storage is already faster than any known type of storage
Levi Lapsley Gimme that cash/cache XD
(Not the same of course)
And I just installed 10/100 Ethernet. I didn't even know there is 10Gbit/s until this Video :/
Maybe using a Linux or BSD would work better? I would never trust Windows for performance...
(Also, I am aware that there are others, but those are the ones I know that are best for networking)
Yeah apparently you don't know shit so shut the fuck up.
For those who won't need RJ45-specific cabling, then I just picked up an Emulex P004096-01K network card with 2x SFP+'s for $50, and a 48-slot Quanta LB4M switch with 2x SFP+ uplinks for $95
That's $145 in ebay money (excl. ship n tax) for a cheapo 10Gbit setup.
Dunno whether someone has mentioned it, but if the MTU on both ends doesn't match, you'll end up bottlenecking at the switch, cause it would need to repackage every single freakin frame (I've run into this multiple times with corporate clients). Also the first thing you do whenever you get above 1GbE is to setup jumbos and increase the Rx and Tx buffers. TOE also helps. The faster/slower transfer inconsistency with spindle drives is usually due to the block sizes discrepancies or lack of fine tuning (depending on the majority of files being stored it makes a HUGE difference whether you're running with 4K or 512K blocks), but since you're using SSDs and RAM disk, I honestly have no idea what might be the reason there.. Also if you're using Windows all across your infra and have enough ports, given the fact you have dualport cards and especially since they're 10X (meaning rj45), I would consider LACP or some sort of balancing trunking - LACP would be best for Win8+ and WS2012r2+ (completely new network stack on both). I could get into more detail if you're interested why LACP and so on, but I guess that's enough for now. Cheers!
Is it me or does Linus talk really really fast in this video
He does, and his voice breaks more than my rj45 clip switches.
He always talks fast, especially when he gets excited!
1Gigabyte has 1024 not 1000MB !!! plzz thos 24MB count!
+Fify Lv 1000*
actually they changed the standards like 17 years ago, 1 Gigabyte = 1000 Megabytes, but 1 Gibibyte = 1024 Mebibytes
Wow didnnt know that :(
+A CuteTeddyBear but gibibyte is
***** I said Gibibyte, not Gigibyte...
relax dude your going to bust a vein
10Gb networking really is quite tricky to get right. You are on the right path with the receive side scaling (if you do not use that, all networking is done on core 0, which coincidentally is also the one used mainly for the OS itself, and even with the latest CPU, you won't get more than about 4Gb/s out of one core alone). Since you are using a 2 port card - have you made sure that the receive queues do not use an overlapping CPU core set? You can set a max processor / base processor number for each NIC, try using something like 2 to 8 for one NIC and 10 to 16 for the other for a first test and 4 receive queues for each (only even numbers=physical cores count). With Intel drivers, you should also be OK using all the offloading features. If you are using jumbo frames, make sure they are active everywhere (even your NAS). Also make sure flow control is active on the cards and on the switch ports, it helps a bit. Does your NAS support SMB3 if you're using Win10 / Server 2012R2 clients? With the exact same card you are using, I am getting live migrations with 2x9.8Gb/s utilization between Hyper-V hosts (SMB3 multichannel over two ports in different VLANs), so it is definitely possible :-)
Me and my friend were amazed in 1994 November when we both got 28.8 modems. He came from a 14.4 and me a 2400. We were so excited to see the numbers spin on a file transfer. Then we found IceZmodeM and you could type to each other during file transfers!! TYPE. TO. EACH. OTHER!...So amazing.
In a city in NZ you can get 1GB/s internet speeds
and in some places in that town its up to
6GB/s
Luke Jamieson bullshit
That's horseshit.
which city brother
I'm in Auckland and I have gigabit lol
lol you guys on drugs we have it here in the us, xfinity has it for a fair price+
Intro: a byte is 8 bits not 10... (Kind of strange... Or is the remaining 2 gigabits for sending addresses and stuff?)
Plus it's 1,024 megabytes to be a gig.
+New American Fishkeeper funnily enough it actually isnt. You're referring to a 'mebibyte', but everyone calls them megabytes
@New American Fishkeeper
that's not a gigabyte, that's a gibibyte
Not 10, because 1->2->4->8.
It's more likely because you always have a certain overhead on any network. So you would never ever get 100% theoretical value. Hence why 80% better reflect what you can expect in real life
We have had 10 gig for years @ work, using sfp+ and om2 multimode fiber. If we are transferring lots of tiny files, the performance is never very good, single giant files are always fast. I'd check your server to see if any kind of read-ahead and write-back are enabled on the array. Stripe size of the raid(s) can also make a huge difference when writing. For giant files like you describe, I usually make an array w/512K stripes. The higher stripe size always seems to affect write speed, not so much read. I took a local ssd array and changed it from 64 to 512 and got 1600 - >2200 MB/'s difference on writes. Anyway, good luck on your 10gig network!
Linus, do you think that the length of the cable run from your test bench to the server/switch room had something to do with the variable speeds? Have you tried it right beside the switch? Maybe the quality of the connectors used in the network installation might contribute.
The one thing I can think about with having this much speed is virtualization especially if you want to stream enterprise apps to all of your users as well as doing a NAS setup.
Two questions: #1 "More higher", can you really say that??
And #2 A single SSD may be limited to the 600MBps limite but what if you are running RAID?? Genuinely curious...
I thought for a moment that Linus would be building a PC while underneath the desk.
You guys should do more networking videos. I think you guys are very entertaining and believe you could bring some humor to the subject that could make it less painful.
I have always been told that networks at that speed can not be actually handled due to the length of the able, if you ping one PC to the other you will get
0:48 Forgot to grade? Or title sequence overlay effect still happening?
Dream comes true in 2018 nov 1st: native 10Gbps lan in Korea (of course South korea lol)
10 gbit networking comes pretty close to uncompressed video and audio transfer over long distances.
Imagine gaming on a computer miles away at the exact same speed as if you were sitting in front of it
I wish it was talking about the internet 10 Gigabit.
Dang I wish.
4k+ Streaming.
+Ironz Ingotz You could do that with Gigabit. I can with a less than 50 MB/s connection speed on especially compressed videos.
This is awesome, I'm currently in the middle of putting together my own fast Home network! Thanks for all of the tips and tricks!
Can you produce a network diagram/explanation for your whole office?
when you get excited, you sound just like VeggieTales
Everyone knows that the human nose can't see over 274mbps.
Funny how this is now so close to being cheap enough for every household
I forgot how high piched Linus's voice used to be lol.
consumer grade....linus should check out infiniband FDR for some fun.
zed star yeeees
7:40 WIndows does not have very stable networking, I recommend using linux (specifically a server distro, since they're designed to support crazy networking shit like InfinityBand [400Gbps])
I don't know the details of the server hardware configuration, but if my understanding is correct he's running FreeNAS, whith ZFS, on a hardware RAID array. That may be adding some IO delay. Enabling jumbo frames on the network would be the first step as he did, but I don't think the bottleneck was ever on the network because with wire speed switching you should have no trouble achieving max throughput.
oh yeah if your frame/MTU sizes are different, the individual frames will get broken up along the way and have to be reassembled, this will add tremendous overhead and in that case the bottle neck would be the network.
Won't these speeds bottleneck the HDD and some SSD (without RAID) writing speeds? xD
Imagine a glass desk top with the PC in a case underneath. THAT would be awesome
6 years later I’m actually looking for how to video :)
Jumbo packets barely do anything. A 1500-byte MTU is already like 3% management overhead. A 7500 MTU won't decrease that proportion by much.
turning off flow control fixed the inexplicable slow downs for me.
update this video with what you are using now
Mega Man
Am I the only one who thinks he sounds like Steve Carell?
Your SSD SAN is likely the bottle neck. We have EqualLogic SAN's at work (over $500K a pop) that easily do 10Gbit/sec from one server to another using 10Gbit NICs. Of course we are using Dell's N4000 series 10Gbe L3 switches. Our SAN space is over to a pedabyte.
This UA-cam channel is good because this guy shows that homosexuals can do more than just interior design or hairdressing.
Linus, there are HUGE performance differences between software RAMdisk solutions; please investigate that further, the free tool shipped with my mobo (asrock's AXTU with xFast RAMdrive) is the best I've tried out of 4. 4k writes differ over 500% between the lot.
@LinusTechTips
Make sure both the PC & server is set to high performance mode. I'm not 100% sure if you can tweak the SMB buffers on windows, but for my FreeNAS based server with bonded 10Ge, I needed to raise the SMB buffers significantly before I got good throughput.
Also, do note that because SMB is single threaded it has interesting behavior to say the least. You'll notice that if you have a client doing multiple transfers at once, you'll be limited to the slowest connection. So let's say you have a theoretical 700MB/s limit, but for some reason one transfer is going at 100MB/s, the other transfer will be capped at 100MB/s on the windows client. If the slowest transfer goes up, as does the other one.
Once that was done, and the client machines weren't in low power states, I was capable of pushing 700-800MB/s on spinning disks from our ZFS servers.
i get about 3 MB/PS if im lucky
That 'Politically Correct' picture at 1:45 with a semi-black man, 4 women of whom 1 has a fucking afro and one has to be blonde, the barely visible BUT VISIBLE asian man and the 2 white men to make it more realistic. The fuck has this world turned into.
Oh, one more thing. The XS712T has a bug on the new firmware when you run LACP on the SFP+ ports. Sometimes the balancing algorithm will decide to spew lots of heartbeat frames and essentially bottleneck the connection.
I haven't seen this happen on the copper ports, but who knows. The latest firmware also quiets down the fans too :D
It is fast, very fast.And what is fastest ? :-)
Why not Cat7? More shielding and not that much more expensive (Dollar per cable I think, buying in bulk = cents)
x540-T2's are currently around 100$ on ebay.
Linus your complaining with 10Gbps. I HAVE 2Mbps WITH A SISTER THAT CONSTANTLY WATCHES NETFLIX AND IT STOPS WORKING 6:30pm to 10:30pm.
