I have a Radeon Mobility 9200 and the performance of EXA is very uneven. 
When it works as it should it really flies, but now and then it slows to 
a crawl. I'm guessing memory usage is an issue because the desktop 
window is the one causing most grief. A simple things as hovering above 
desktop icons (making them light up) causes the system to lock up for a 
second.

I've tried the settings you suggested but it didn't have any effect. Any 
way of diagnosing the problem?
