4-core slow due to disk access

[Alvin Thompson]

There was a HUGE memory leak with one of the graphics/compiz drivers (I 
can't remember which one). The maintainers reverted back to older 
drivers very recently to fix the problem. Try updating your system to 
see if the problem goes away.

Anyone remember what driver that was? I remember they reverted back to 
version 1.2 but can't remember which it was...

Hope this helps,
Alvin
