Real-world JEE performance troubleshooting & tuning: Tips n' Tricks

Performance tuning any application is a black art that can consume much time. Fortunately, Java has many tools that can aid in this effort. There also are a number of basic tips that can help to analyze and fix performance problems. The Java memory model is usually something that you don't need to tune, but for high performance applications it is necessary to tweak. While there are a number of advanced things that can be done to performance tune an application, we'll discover that the simple, basic things are all that are usually needed to make your apps fly.

This session looks at how to setup and run an application with profiling tools and monitoring tools. We'll setup an application to run and put it under heavy load. While running, we'll interactively monitor it and look for problems and how to go about finding and fixing them. We'll also cover the basic issues you should look for when performance tuning.
We'll look at memory management and how to tune it appropriately. We'll also look at some of the Java 6 tools available to monitor performance and look at the JVM internals. We'll focus on the simple things that can be done right away and then look at some more advanced tweaks to identify and fix performance issues. Along the way, you'll learn some of the tips and tricks to performance tune.
