Troubleshooting MySQL Performance
Query runs slow, all threads are stacking for ages during peak time, application suddenly started run slower than before, ... This is long and not complete list of performance issues you can experiment. Are you curious why your MySQL installation does not work so fast as you wish to? In this session I will demonstrate troubleshooting techniques which can help you to solve common performance problems. We will study why query runs slow on itself, how concurrent connections affect performance, effects of hardware and operating system enviroment as well as influence of MySQL server options. I will prefer to use built-in instruments and tools which come together with MySQL distribution as higher available, but don't stack with them and also discuss those great third-party tools which have not analogues. You will learn how to choose a method best suited for particular problem and effectively use it.
