Here at work I just reformatted my computer to move to linux from windows.
I am running IDEA 5.1.2 (havnt upgraded our license yet).
When this same version was running on windows up until this week it was lightning fast. Now with linux IDEA is unusably slow. Typing takes 2-4 seconds before the text shows up on the screen, any kind of GUI interaction with IDEA just kills my computer.
There is no anti-virus or anything running, the box is pretty much a pristine RedHat EL 5 installation.
I've browsed around these forums and seen NUMEROUS threads about horrible linux performance, and there seems to be some correlation with the nvidia xinerama drivers. I have the xinerama drivers running dual head as well.
Ive tried running IDEA with both the java5 and java6 JREs, and it doesnt matter.
I need some insight into why IDEA is running so slow or my whole development team is going to have to switch over to eclipse, which runs just fine.
