Diagnosing and Fixing MySQL Performance Problems

Average rating: ****.
(4.33, 18 ratings)

The typical trial-and-error approach to diagnosing and solving performance problems breaks down when the problems are difficult. As the complexity of the problem increases, so does the need for a methodical approach and powerful tools. This tutorial will teach you how to be systematic.

We’ll run through the process and then emphasize getting to know your toolkit, including iostat, vmstat & mk-query-digest. You will learn the approach Percona consultants have put to use across thousands of customer machines.

We’re going to try and teach you to be as practical as possible, with only minimal emphasis on performance theory where it’s needed. The main focus will be on MySQL versions 5.0, 5.1 and XtraDB on Linux operating systems. Attendees are encouraged to bring laptops as there will be some interactive components.
