If you tried optimizing for the Opteron and used a decent compiler with decent options it'd do a lot better. The P4 isn't worth a crap without specific P4 optimizations and SSE2 support. That is a fact. You're comparing against a 32bit non-PGO binary for the opteron with absolutely *NO* optimizations. No way you can say, "My Xeons are faster". >> What kind of #s does a dual Athlon >>1.8GHz get?
