Sun Java System Portal Server 7 Deployment Planning Guide

Basic Tuning Techniques


Note –

The tuning settings discussed in this section focus on Portal Server residing on the Solaris platform. However, the principles can be applied to other generic Unix type operating systems.


Table 8–1 below lists the performance analysis tools that will help in providing feedback for tuning the Portal Server and its web container. In addition to performance issues, many of these tools can be used to detect other types of bottlenecks at the overall operating system level.

Many tool descriptions provide sample output, suggestions for interpreting output results, tips on improving output results, and links to related sites.
