Google a bit for adjusting GC settings in idea - stuff like http://blog.jetbrains.com/idea/2006/04/configuring-intellij-... (old, but check the comments). I'm not using it anymore, so can't find what I ended up with, but adjusting the startup options made a huge difference 2 years ago.

I think I also went for one of the experimental/less stable concurrent collectors - didn't find any issues in practice.

+1 I bumped up heap space to min 1g max 2b. Now this beast of a Spring heavy project (day job) doesn't hang IntelliJ ("indexing...").

Seems to me these IDEs could suggest reasonable JVM options after profiling your project.

Or at least put the JVM options in the preferences, so I don't have to dig around the install/distro.
