More memory will help, but just as important is adjusting the garbage collection algorithm and disabling the unnecessarily paranoid class verification that java does: http://davidsalter.co.uk/blog/?p=332 http://davidsalter.co.uk/blog/?p=332 Here's mine: -XX:PermSize=256m -XX:MaxPermSize=256m -XX:+UseConcMarkSweepGC -XX:CMSIncrementalMode -XX:CompileThreshold=100 -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -Xverify:none -Xms1650m -Xmx1650m Edit: Yeah, 1650m is way more memory than I really need. I'm just fortunate enough to have 8G in this machine so I had plenty to spare. Edit again: I use emacs in Terminal to edit /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse.inito add these parameters
