Kernel Recipes 2017 - Perf in Netflix - Brendan Gregg

Linux perf is a crucial performance analysis tool at Netflix, and is used by a self-service GUI for generating CPU flame graphs and other reports. This sounds like an easy task, however, getting perf to work properly in VM guests running Java, Node.js, containers, and other software, has been at times a challenge. This talk summarizes Linux perf, how we use it at Netflix, the various gotchas we have encountered, and a summary of advanced features.

[@Jiawii]

Is he running perf on a Mac? I though it was only for linux.

[@pervognsen_bitwise]

No, he's using ssh to run it remotely.

Crappy mic and the guy walking around in the background make this hard to WATCH or LISTEN to.

Why the f()ck are the speakers NOT wearing wireless mics? Pickup up and putting down that handheld mic is just stupid. The event organizers need to be taken out back.
