How are they handling the multiprocessor configurations compared to a Xeon? Is there a performance hit? Are they really Xeons and not P4s? >Also there are xeons and xeon-MP versions.

There is one significant difference. Price. :) Has anyone run crafty on an MP system? Any idea how a 2 GHz MP would compare to a 3 GHz Xeon? Regards, Keith
