Profiling: comparing pt-pmp and perf tools on real examples
Hello, tekkix! In the previous article, the primary analysis of the application was discussed, which tools should be used to collect information and how to work with these tools. Let me remind you that we were talking about two utilities: poor man's profile, which allows you to comprehensively evaluate the application's performance by displaying off-cpu and on-cpu parts; and perf, which has high accuracy and powerful functionality overall. Both of these tools are used for performance analysis, as their combination allows you to examine the "patient" from all sides.
