I have performed the test under Linux Fedora Core 3 and Windows XP
Professional SP2.
This is the info about my system and Python (from /proc/cpuinfo):

Under Linux The python version is 2.3.4 (release 11) stock Fedora 3 RPM 
(compiled from python-2.3.4-11.src.rpm)

Under Windows the Python version is 2.3.4

Anyway I will try to build the latest version (2.4) from source using 
the best possible optmizations with the gcc compiler.

Being the pystone a benchmark that exercises mostly the compiler 
optimizations I wonder if there is a benchmark that could bring up the 
whole capabilities of the operating system (I/O, multithreading, memory 
allocation, etc.).
