2103 unusably slow


I'm getting a lot of 100% CPU spikes on 2103 under Windows XP. It would be intermittent during editing, but easily reproducible by moving IDEA into the background. Pulling up another application while IDEA was running would invariably cause a 10 second spike of 100% CPU. Anyone else seeing this? I did clear all the caches and VCS history, but no joy.

Hi Dave, I have been seeing this first in 2097.
It's so bad that I am back on Idea 4.0.3 - though I know that EAP version can have rough edges and have been using EAP version with quite some serious bugs in it. But this is just too much, because there is no workaround available.
I filed a tracker entry, but it has not yet been opened (or even assigned):
http://intellij.net/tracker/idea/viewSCR?publicId=34206

You might want to compare thread dumps against those that I posted to check if it is really the same problem.

When 2103 came out I did a completely fresh install of it and found it still has the bug.

You must hate me as a person not having this problem, but can you point me
to a scenario so that I would be able to see this problem?

For it's also quite ok, without any visible delays in perfomance.
the only thing I found out is that CVS update command sometimes hangs in the middle of the process

Why should I? It's more that I envy you ;)

I thought it has something to do with my project size and setup (35 modules), but then I had the very same problem with a tiny little project.

The best way to reproduce it is clicking "x" on Idea's main windows: It hogs the CPU for 30 seconds without any UI feedback. It also happens very frequently after I start my program with Debug or Run and Idea looses focus to my own frame.

Seemingly a JetBrainer has isolated that problem:
My workspace file (*.iws) was nearly 8 MB in size with most of it occupied by information from structural search plugin.
Probably if you never used structural search you wouldn't have the problem. A fellow was using the very same project and had only a 98 KB workspace file.
I deleted the iws file and for now it seems much faster.

See the tracker entry http://www.intellij.net/tracker/idea/viewSCR?publicId=34206

Got it. My IWS files had grown to multiple megs. Unfortunately, I didn't get this message until after I had done a full "scrub every bit of IDEA off your hard drive and refresh from the latest EAP" reinstall. It may take hours to get my settings back exactly the way I like them...
