Folks, just installed Mathematica on new Windows 7 64-bit machine and
Benchmark[] is much slower than on 32-bit Windows XP. MathematicaMark7
Rating of new system is 1.13 compared to 4.12 of old system.

Any explanations for this? Details are below. Are many of Mathematica's
routines still in 32-bit and thus slower on 64-bit machine? Is this an
issue related to Windows XP compared to Windows 7 vis-a-vis Mathematica?

Needless to say, new system is much better in terms of CPU, memory, etc.,
so this result is very surprising to me. I'd like to know what I can
adjust to get a blazing Benchmark!
