[opencms-dev] serious performance problem

[david.van_den_brande at the-ecorp.com]

Hi there,

We are facing a serious problem performance problem in OpenCms 5.0 ...
We ran a simple test scenario ("refresh Home.jsp file 10 times") with
LoadRunner. 
Here are some results:
1 user : 
- scenario execution time: 25 secs 
- CPU usage by java process: 25%
10 users : 
- average scenario execution time: 3 min 45 secs 
- CPU usage by java process: 55%
The high cpu usage of the java process seems to indicate that opencms is not
able to process jsp's, composed of several other jsp's, in a performant
way!?
Some information about the Home.jsp file, as used during the tests:
- uses a jsp template (look & feel + navigation jsp + "calendar" jsp +
"poll" jsp)
- includes 2 jsp's to show some news items and related information.
Other :
- OpenCms version: 5.0
- Server: Sun Solaris (2 CPU's)
- Database: MySQL 4.0
- Application server: Tomcat 4.1.24
- JAVA_OPTS (catalina.sh) : "-Xms128m -Xmx512m"
Does anyone have a clue what the problem could be, ...and how to solve it?

Thanks in advance!!!

David
