Performance Analysis Methodology

A performance analysis methodology is a procedure that you can follow to analyze system or application performance. These generally provide a starting point and then guidance to root cause, or causes. Different methodologies are suited for solving different classes of issues, and you may try more than one before accomplishing your goal.

Analysis without a methodology can become a fishing expedition, where metrics are examined ad hoc, until the issue is found – if it is at all.

Methodologies documented in more detail on this site are:

The following briefly summarizes methodologies I've either created or encountered. You can print these all out as a cheetsheet/reminder.


I first summarized and named various performance methodologies (mostly developed by me) for my USENIX LISA 2012 talk: Performance Analysis Methodology (PDF, slideshare, youtube, USENIX), then later documented them in my Systems Performance book, and the ACMQ article Thinking Methodically about Performance, which was also published in Communications of the ACM, Feb 2013. More detailed references are at the end of this page.
