You did not mention which level of JVM you are using. I assuming Sun JVM 1.4.x, and if so here are some suggestions.
First, did you specify a young generation size? Typically, you will want the young generation to be about 1/3 the size of theh eap. Assuming your 100MB heap size, the command line would be "-Xmx100m -Xms100m -XX:NewSize=33M -XX:MaxNewSize=33M". Proper young generation sizing can lead to a significant performance boost. Have you monitored garbage collection using -verbose:gc (or any of the other commandl ines)? See http://wiki.jboss.org/wiki/Wiki.jsp?page=SPECjAppServer2002TuningComponentsJVMMonitoring for more information. Such monitoring will usually let you know if you have properly sized the heap. Finally, any possibility of adding more memory to your servers? If you upped their emmeory to 1GB, you could run a 600MB heap which could give you a significant performance boost.
