I've got Ubuntu 7.10 on my machine with Sun's JDK 1.6.0.03 with IDEA_JDK set to use that version of the JDK. As far as the hardware setup goes, it's a Dell Precision 390 with 2GB of memory, a 1.86GHz Intel Dual Core processor, and an nVidia Quadro NVS 285 graphics card using the restricted drivers from nVidia (if any of that matters). I currently have this in my idea.vmoptions file:
With this setup, Intellij 7.0.2 is downright unusable. The IDE frequently pauses while I'm typing, freezes for about a minute when switching back and forth between applications, can be unbearably slow during debugging, takes about a minute to become responsive after making changes to the project file, maxes out CPU usage, and often runs out of memory no matter how high I set the cap. I tried adding "-Dsun.awt.keepWorkingSetOnMinimize=true" to idea.vmoptions to get around a supposed JDK 6 issue mentioned in another thread. I'm not sure what I can do at this point to get things running smoothly.
A couple of thread dumps are attached, let me know if there's anything else needed to track this down.
Anyone else having these issues on a similar setup?
