Pete, re: "It just goes to show that P4 (and its descendents) is a terrible server CPU unlike Athlon that loses far less or gains somewhat when pushed with high loads."

Some data which demonstrates the effect of high load (though not server type apps) was presented in Anandtech's original Athlon MP article here: anandtech.com

The results for the IT/Constant Computing Performance at three loading levels were presented and the results showed the Athlon MP performing better with increasing load.

EDIT: I cannot recall any good server type test results for increasing loading level.
