Linux Systems Performance

The talk is about Linux Performance Analysis and Tools: specifically, observability tools and the methodologies to use them. Brendan gave a quick tour of over 20 Linux performance analysis tools, including advanced perf and DTrace for Linux, showing the reasons for using them. He also covered key methodologies, including a summary of the USE Method, to demonstrate best practices in using them effectively. There are many areas of the system that people don't know to check, which are worthwhile to at least know about, especially for serious performance issues where you don't want to leave any stone unturned. These methodologies -- and exposure to the toolset -- will help you understand why and how to do this. Brendan also introduced a few new of these key performance tuning tools during his presentation.

Very impressive presentation about measurement and metrics!! Can't wait for "Systems Performance" [book]. If you like this video, then you will love Brendan's slides (on slideshare)

Nice talk Brendan, I recognised you immediately because of your video about shouting in front of disks bays :D

You're welcome, and sorry. Most of my videos are filmed under poor conditions with amateur equipment, working around or at least with no help from any A/V crew. So... we do the best we can with what we've got.

First, THANKS for giving this talk and sharing the recording. My team watched earlier today. This is a great talk, but the video is hobbled by 2 production problems: Slides and sound.

Slides had too little screen-time: Very frustrating to just begin absorbing the information on the slides only to have it cut back to BG. This really only needs sound + slides. (PDF helped)

Sound recorded from mic on cam instead of BG's headset, so it was hard to understand.
