Idea X stresses X-Org window manager opening "console" windows
If I open a console window, like run or testng, my xorg process spikes to 100% CPU for a few seconds and this causes my system to become unresponsive. 9 does not have this behavior (may spike xorg a little, but not noticeable without watching top). Use the same JDK and settings for both.
Running Ubuntu 8.04 and JDK 6u21x64.

Hi Charles,
This can be related to this problem.
You can provide us CPU snapshot in order to ensure that.

My symptoms are nothing like this. It is only on opening windows. Once opened, everything is snappy. But, I will try to get a cpu snaphot for you.
Here is the CPU snapshot from 96.974.

I think it may be more closely related to http://youtrack.jetbrains.net/issue/IDEA-57881. The symptoms are more similar and based on the timings, it is not consistent.
Hi Charles,
IDEA editor uses almost custom painting and the snapshot shows that java2d operations take a lot of time.
I'm under ubuntu 9.10, jdk 1.6.0_19x64 (quite lazy to upgrade) and don't see such performance degradation. Can you try the use-case under java 1.6u19?
Meanwhile we'll try to improve performance of IJ-specific operations.

There are no issues with JDK 6u20x64. It is faster then 9. So, this looks JDK dependent.
Cool, thanks for the info!
