Default I got better performances under x32 than x64?

This is what I got:

XP32:

Mem BW 6575 MB/s (integer) and 6571 MB/s (flotting point)

CPU---60,649 MIPS and 42000 MFLOPS


XP64:

Mem BW 6448 MB/s and 6443 MB/s

CPU---47,966 MIPS and 40,284 MFLOPS

Is someone can explain the performances of XP64 vs XP32?

What about XP32 vs XP64 vs VISTA32 vs VISTA64?

Programs running in 32-bit emulation mode will be slower on a 64-bit system than a 32-bit one.

I ran XP x64 for a few months, it was a wreck in my experience, running Vista 64-bit now, and having a much better time.

I haven't had a single problem with XP 64-bit yet. Scores seem to be bangon with 32-bit also.
