I'm working on a big rule engine project. After deployment of rules and xom rule execution server doesn't respond or its response time gets longer and sometimes it freezes.

I set heap sizes on WebSphere server like this: **-XX:MaxPermSize:1024m -Xms2048m -Xmx2048m**

Is there any other way to configure it to perform better? Because sometimes I have to restart the related computer to work it safely.
