Using Sys Internals FIle Monitor program (http://www.sysinternals.com/utilities/filemon.html), I noticed that
IDEA was constantly accessing the icons.jar up to 10 times per second, even when IDEA was iconified.
I hadn't see this when I ran FileMon before, although it was awhile ago; I forget the last EAP build I looked at this.
Anyway, IDEA seems to be chewing up some cpu with the constant accesses. Here is some sample output from
FileMon. Hopefully you can track down while it keeps reloading these icons..
Also, I would recommend adding a "Performance" componet in Jira since I think Performance issues are very
important, esp. when performance is slower than the previous release. It would be nice to have it's own category.
