the P4 does not seem te be equaly efficient with it cycles as a P3 ;-)

see e..g here, second diagramm and the text below:
http://www.sysopt.com/reviews/pentium4/index4.html 

in addidtion to that different compilers (and options) might explain a 
bigger difference. i assume that you used the same python versions and no 
other CPU hogging processes...
