Inge, The SE should be a client version and designed for quick GUI start-up. Whereas the EE version is the "server" version and starts slower, but is designed for long-time running. They have different garbage collection strategies.

When I said "performance gap", I meant for example starting tomcat in 5 sec instead of 20 sec, much faster eclipse, and so on. I'm a little confused when downloading JDK from Sun's pages, does it matter if I download SE or EE? Does it matter at all what JDK version I download, or is this only a question of configuring it correctly when installed? I already have tried setting a couple of VM parameters on both eclipse, tomcat and jboss on startup, and gotten some minor improvements on OutOfMemory crashes, but I would love to try to increase the actual speed performance as well. I will try to read a bit and get smarter on this subject :) For reference, here's my Eclipse startup on my Windows XP machine: C:\dev\eclipse\eclipse.exe -data C:\dev\eclipse_workspace -vm C:\dev\jdk1.6\bin\javaw.exe -nosplash -vmargs -Xms128m -Xmx256m -XX:MaxPermSize=128m Thanks again!
