I've run nginx serving as reverse proxy in the 30K r/s range for production workloads, the way nginx handles tls is kind of naive and could be improved. Basically what is happening is that there is almost always uneven distribution of work across worker processes and it dogpiles with tls overhead. limiting the tls ciphersuites used can help mitigate this so that there is less variance in how long TLS handshakes take on aggregate. also multi_accept on is you friend.

another amazing performance benchmark and just the one I wanted to see rerun from your old videos. many thanks and great job I'm still curious about the results tho.

This was really interesting, i used to be running Apache alot a few years ago, and like you, i switched for the huge performance benefit of Nginx (in most cases apparently). Now, i don't do any loadbalancing using nginx or apache but this was really interesting to me as HA is always something i have been looking for but never really managed to do (lack of hardware and knowledge in my homelab). Earned the sub well done!
Valuable benchmarks! Tip: There is this insane resonance on the audio of this video (and probably more of your videos), so when you pronounce words with s, I can feel a brief pressure in my ear from my brain trying to regulate the intensity. 😅
Amazing test I did the same test with Grafana K6 but between Nginx and Openlitespeed. Your test definitely explains why cyberpanel is the most performant out of the open source hosting software I tested. it uses a combination of apache and openlitespeed ( I think the perform a reverse proxie with apache and serve the website using openlitespeed )
We had experienced an interesting issue with Go application and Nginx when migrated from Pyhton to Golang, that Nginx uses A LOT more tcp packets to communicate with golang apps, at first it overloaded a load balancer cluster and then the application itself, we still haven't figured out what happened, because we also were in the process of migrating to Traefik, but it looks like Go and Nginx really want to split requests into a lot of packets since the most load came from TCP reassembly, and there were a lot more sockets in waiting ACK then usual.
Given my exposure to both apache and nginx, this lines up. You want something to serve static content nginx is king. I am concerned about what is happening around that 80% though. The way I see them nginx is like a scythe able to cut through a metric boatload of requests and apache like a swiss army knife with a boatload of tools available to do everything that has ever come up in my travels (this is where I sense apache's slowness comes from, its versatility). I guess the car analogy is nginix can do a 1/4 mile straight faster but apache could do a rally better as its more adaptable. I have a non-compliant endpoint that uses api_key HTTP header and it took effort just to get nginix to leave it alone and then I route that path to an apache container where it gets fixed.
i have found i can make nginx do everything apache does, including serve php and all that application-layer stuff people do with apache. it's not especially advisable, though.
@@MattHudsonAtx the invalid header issue I mentioned I haven't found a way to do it with nginix, at best I can get it to pass it through for something else to deal with using the ignore_invalid_headers directive. Given I was trying to stay just using the nginix proxy manager which is handling everything else I would love to know an alternative way.
I wonder if apache and nginx use a different default compression level. The test results hint at this (even though both state 6 as default in their docs), and diminishing returns on a higher compression level might be hurting apache in this test. There might be some improvements investigated by skipping compression on files less than 1kb (which I think is a best practice), as well as setting the same gzip compression level on both services.
OpenResty is supposedly more performant than Nginx in serving dynamic webapps -- any chance of Nginx vs. Open Resty? Huge thanks for amazing regularly updated benchmarks.
Ok thank you very much for really providing these insights! I was in the making of my own reverse proxy, and this is some key data. I think I might have made a RP better than both of those. 😏
When looking at the 85% cpu breakpoint, one thing I could think of was some form of a leak, maybe try to slow down the request increase rate, it might show different results.
Why not? Don't you think most people will use the default settings? Imo this way of testing is probably the most representative of real world performance. Of course it's also interesting to see how far you can optimize, but this is definitely useful.
really great video! can you do a nginx vs tengine next? it claimed that it has a better performance than nginx and I'm very curious about it, love your vid
Saya pikir orang Indo, ternyata bukan. But it's a great video (and I'm still sticking to Apache - PHP MPM coz I've never had such a huge traffic... except for the DDOS event).
For the reverse proxy tests, can you test with the swiss army knife of reverse proxies: Envoy proxy? It supports TLS, mTLS, TCP proxying (with or without TLS), HTTP1, 2 and even HTTP3, multiple options for discovering target IPs, circuit breaking, rate-limiting, on the fly re-configuration, and even Lua scripting in case all of that flexibility isn't enough.
I would like to see a test with NGINX Stream Proxy Module which acts as just a reverse TCP or UDP proxy, not as a HTTP proxy. I for example, use this for some game servers where I reverse proxy both TCP and UDP packets. I setup NGINX for this because it seemed like the easiest thing to do, but I don't know if it has the best performance.
i use event more, here is origin config - github.com/antonputra/tutorials/blob/219/lessons/219/apache/httpd-mpm.conf#L5-L12 i also got a pr with improvement - github.com/antonputra/tutorials/blob/main/lessons/219/apache/httpd-mpm.conf#L10-L18
Did you use RSA or ECDSA certificates? Because ECDSA should be used most of the time, as they are faster to transmit (less bytes in TLS handshake). Also, nowadays, when used as Reverse Proxy, the connection to the backend servers (i.e. downstream) should be also encrypted, and not cleartext.
I used RSA in both proxies, and regarding the second point, it's good to have but difficult to maintain, you constantly need to renew the certificates that the application uses.
took me a while to realize this isn't OSS nginx, have not played around with the F5 one, does it come with its builtin metrics module ? or what did u use to export those? great content as always!
@@rafaelpirolla makes sense that latency was obtained from clients, thank you!! worked around this once using otel module + tempo metrics generator, but that was rather convoluted / unsatisfactory approach
yeah, it's open-source nginx. Also, the most accurate way to measure latency is from the client side, not using internal metrics. In this test i collect cpu/memory/network for web servers using node exporter since they are deployed on standalone VMs
Something isn't quite right here. In all 3 tests, you show the requests per second synchronized until a major failure happens. The time log at the bottom seems to indicate these requests per second metrics are being gathered over the same time period. Yet how can this be possible when one web server has a significantly higher latency, measured at the client, than the other? Once the latency difference hits 1ms, that means we should notice at least 1,000 fewer requests per second for each second that passes after that moment -- accumulating as time goes by. And, of course, this difference should accumulate even more quickly the higher the latency goes. It looks to me like you (accidentally?) decided to normalize the graphs of each contest so the RPS would match until one of the servers failed. Or if not, what am I missing here?
Is it possible to benchmark pingora as well? It will be easy to use it after river became available so will wait for it in future! Thanks a lot for the benchmark!
In the last test, are the Rust applications running in the same instance as the server? It seems like the Rust application in the Nginx case is stealing processor time to the server.
I've noticed this weird behavior of nginx as a reverse proxy to a backend server too. Even if that backend server itself is just serving static data, the mere act of being a reverse proxy seems to cause a rather big performance hit for nginx. Weird.
I didn't get the question. You use compression to improve latency and overall performance. With a payload that is four times smaller, it takes less time to transmit over the network.
I feel like network usage in itself is related to request/s, in that if one webserver is able to satisfy more requests per time, it's prone to having more network usage within that same timeframe. Why not network usage per request?
