Quite often when teams are faced with the pressure of dealing with poor performance, the first instinct is to revert to those development techniques that are all so like your favorite pair of slippers. The problem is, it is almost impossible to diagnose a performance problem using static analysis of the code. To be successful (rather then lucky) one must be able to acquire dynamic data from the runtime and then be able to understand what that data is telling them. This talk will dive into how one can instrument J2EE/J2SE applications to diagnose performance problems. But since power point slides are cheap, we will minimize time looking at them in favor of spending more time solving performance problems together.
