Hi Paul,

We have noticed a similar problem, running OpenCMS 5.0.0

RedHat 8.0
Apache 2 with mod_jk connector
Tomcat 4.1
IBM JDK 1.4.0

Are you using the SUN JDK, IBM or another?

At this point in time we are unsure of where the real issue lies, so I can't
any tuning tips at this point in time.

We have been noticing a gradual performance degradation in the OpenCMS 5.0
RC2 workplace running under Tomcat on Redhat Linux 8. With two users editing
documents over a period of 2-3 hours, the workplace slows down to the point
where a complete refresh will take up to 60 seconds.
The Server has 512Mb of RAM and 1Gb of swap space.
Our current JVM runtime parameters are:
-Server -Xincgc -Xms256m -Xmx256m -XX:NewSize=128m -XX:MaxNewSize=128m

Has anyone got any tuning tips for use with OpenCMS?
