Question : Tomcat Performance Tuning

Hi Experts,

I have a default Tomcat installation in one of my production environments.  I'm using it to serve an EMC Documentum Webtop 5.3 web application.

The problem is that some navigations are very slow.  Navigating between some pages are 5 to 10 times slower than the same navigation done on the same pages in the same application on a Websphere Application Server (WAS).

Are there ways that I can customize/configure Tomcat to allow for faster browsing?

Some vitals about my environment are listed below:

OS of Web Server -  Windows Server 2003 R2 Standard Edition SP2
JVM Version - Java SE runtime environment 1.6.0_13
Tomcat version - 6.0.18
Tomcat Initial Memory Pool - 1024MB
Tomcat Max Memory Pool - 2048 MB
Tomcat Thread Stack Size - blank
Tomcat Average session count - 30
Tomcat Applications Served - 1

Hope I didn't miss anything.

Please assist

Answer : Tomcat Performance Tuning

You may need to add the MaxPermSize parameter, it should be Max Memory Pool divide by four.
