It isnt the CPU that is the problem. A lot of code does compositing against
server side image data, and the X servers (except the Nvidia proprietary
one and the Vesa server) implement this in a totally screwball manner
still. The resut is a lot of ping pong bus traffic and on some chipsets
it seems to hurt the throughout of disks, latency of audio, video capture
etc.
