Eclipse too slow and out of memory

Looks like Eclipse PDT was getting quite slow on me, it thinks sometimes 10-15 seconds when I switch between files or save one. My current project is not small one, but still… Looking around for a solutions I found quite easy tip at http://www.eclipsezone.com/eclipse/forums/t61618.html In short – I am now running eclipse.exe -vmargs -Xms256m -Xmx256m -XX:PermSize=64m -XX:MaxPermSize=64m and my Eclipse is way faster. Thanks for the tip, Riyad Kalla!
