hello peter, thanks for your reply, so at the moment the first test includes just the call to a jsp which gives back the date. the database things should be coming later. my actual jvm settings are the following: -XX:+DisableExplicitGC -server -Xms1024m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m -Dsun.rmi.dgc.client.gcInterval=360000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv4Stack=true i am running the server on a 2gig ram machine. does it make any sense to set the values for the heap higher than the actual values? i also already tried some GC options for the jvm (-Xincgc) but there never seem to be any garbage collected... thanks for looking and thanks for the link i will check it out.
