Process Overview

The following table outlines the overall GlassFish Server 3.1 administration process, and shows where performance tuning fits in the sequence.

Performance Tuning Sequence

Application developers should tune applications prior to production use. Tuning applications often produces dramatic performance improvements. System administrators perform the remaining steps in the following list after tuning the application, or when application tuning has to wait and you want to improve performance as much as possible in the meantime.

Ideally, follow this sequence of steps when you are tuning performance:

1. Tune your application, described in Chapter 2, Tuning Your Application
2. Tune the server, described in Chapter 3, Tuning the GlassFish ServerChapter 3, Tuning the GlassFish Server
3. Tune the Java runtime system, described in Chapter 4, Tuning the Java Runtime System
4. Tune the operating system, described in Chapter 5, Tuning the Operating System and Platform
