I suspect in such a test, memory copying speed will be a key factor, I don't have number to back up my idea, but I think Linux has lots of tweaks, such as using MMX instruction to copy data.
I had the oppertunity to study the AMD Athlon XP Optimisation guide and noted their example copy routine, optimised for the chipset, was quite a hell of a lot faster over a straight block copy. Has anyone here done any similar modifications to optimise copyin/copyout? I can't imagine it'd be a bad thing to have.
