IIRC, there was such a question on /. recently. You might ant to look
over there.

I would rather attribute this symptom to a problem in X, where the X
server is allowed to monopolize much of the machine for redrawing. The
fact the our current X servers (all those I tried, even Xpmac_mga
accelerated for my Matrox) eat _huge_ amounts of CPU for all blitting
operations like scrolling etc.

There seems to be work to do on the X side of things....
