Session Presented at 5th IndicThreads.com Conference On Java held on 10-11 December 2010 in Pune, India
Enterprise applications typically comprise of multi layered stacks including the application modules, application servers, the Java Virtual Machine and the underlying Operating System. Consequently the performance of these applications are a factor of these different layers. In the eventuality of a performance problem, it is often difficult to determine the starting point for diagnosis. The Java Virtual Machine is the ‘engine’ for most of the applications. It is responsible broadly for efficient execution and memory management of applications. End users have difficulty attributing the effect of the JVM on the performance of the application. This is because usually JVM is viewed as a ‘black box’.
This talk provides an insight into the key subsystems of the JVM by looking under the hood of a high performance JVM. It ventures onto talk about approaches and techniques for analyzing performance issues. It concludes by introducing the audience to a tool called the “Health Center” which is useful for evaluating and comprehending the JVM behavior of a running application in an unobtrusive, lightweight manner.
Takeaways for the Audience A better understanding of key JVM components, approaches and techniques to diagnose performance issues and performance evaluation using the Health Center
