Just a bit of advice: Please note that current 64bit java vm for amd64/xeon emt64 has serious bugs in HotSpot compiler, so you should better wait until 07 is released: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6346871 regards Leon P.S. You should also consider that the usage of 64bit java will increase you memory usage. > > Now of course, switching to 64-bit OS and hardware may not be an option. > Something that sometimes works for others is to run two or more instances of > Tomcat - with each getting the 1800M of heap.
