[jboss-user] [Performance Tuning] - JVM memory foot print on Fedora

I am running JBoss 4.0.2 with JVM 1.5.0.12, with maximum heap and PermGen memory size set to be 1GB and 256MB, respectively. I deployed JBoss with our application on Fedora 5 (FC5) with 2GB of memory and the memory footprint is as follows: Memory: 634m Virtual Memory: 1712m I then deployed the exact same code and configuration on a similarly configured Windows XP machine, with 2GB of memory as well and Windows version of JVM 1.5.0.12 and memory footprint is as follows: Memory: 331m Virtual Memory: 322m I obtained these numbers right after JBoss start-up while the system is idling doing nothing. Can someone shed some lights on why such a great memory utilization discrepancy on the two platforms? And what do I need to do to tune JBoss/JVM and/or Fedora to bring the memory utilization to a more management level? I tried to Google for some answers but didn't find anything related. Thanks!
