Well, it depends on the jvm memory usage. I use for my system this JAVA_HOME jvm parameters in catalina.sh: -Xms64m -Xmx512m -XX:MaxPermSize=200m It is not certain that this configuration is good for your system. I set 200Mb for max permgen size because the objects in permgen on average occupy 120Mb, but might be too much or too little for you. The same is true for -Xms and -Xmx I suggest you monitor your heap first (by jconsole or jvisualvm), in order to know memory usage by applications, and only then optimize the configuration.
