Chapter 10 – Tuning a Community Edition
server
Tuning a Community Edition server requires you to apply a series of techniques that will
improve the system performance. This chapter provides an overview of how you can tune
a Community Edition server.
In this chapter you will learn about:
• How to monitor a Community Edition server
• How to analyze Community Edition server statistics
• How to make changes to the Community Edition server, JVM, and OS to improve
overall system performance
10.1 Tuning a Community Edition server: The big picture
Figure 10.1 provides an overview of the steps required to tune a Community Edition server.
As shown in the figure, performance tuning usually involves the following iterative multistep
cycle:
1. Measure the performance before you apply any changes to the system by
using the appropriate monitoring tools.
2. Identify possible performance bottlenecks in the whole system. For
Community Edition, the bottleneck might be in the Community Edition server
itself, JVM, or the operating system.
3. Make changes to remove the bottlenecks.
4. Return to step 1 to measure the performance again to see if there are any
improvements.
The cycle ends when the system reaches an acceptable performance.
