I’ve authored an article recently for Fedora Magazine on Performance Profiling in Fedora.
It covers both the basics on how to get started as well as the nitty-gritty details of how profilers work. I’d love for others to be more informed on that so I’m not the only person maintaining Sysprof.
Hopefully I was able to distill the information down a bit better than my typical blog posts. If you felt like those were maybe too difficult to follow, give this one a read.
