Find the performance elephant in the room

Conference

java Java Language & Server Side

How many of you have been tasked with improving performance or solving a performance bottleneck? How many times has the data you gathered confused the situation more than it helped? It is very common for the data to point to a symptom and not the actual cause. During this talk I will discuss a few common performance issues and how they manifest in profile data. For each of the issues I will cover how I gathered the data, my initial suspicion about the problem and what I did to solve the actual problem. The talk will cover JVM object allocation, garbage collection logs, Java and JVM profilers and data structures.
