Tuning the IBM Java Virtual Machine

This chapter describes the use of tuning parameters that are available on the IBM Java Virtual Machine (JVM) on AIX. Because WAS as well as the applications deployed on it execute within the JVM, tuning the Java runtime is a crucial step in optimizing the performance of your applications.

Because each application is unique and may be well-designed, poorly designed, or something in between, achieving performance improvements from following the ideas and recommendations presented in this chapter cannot be guaranteed. However, the chapter introduces the concept of load testing and discusses the use of load testing tools.
