I assumed something like this too. Believing doesn't make it true
though. It turns out Cygwin is NOT the major problem. Running my
program on identical hardware running Linux and the same version of
Python+Numeric, runs about 25% slower than native Windows Python. The
problem is evidently the quality of the code produced by gcc versus
MSVC. There are numerous threads on various groups reporting
comparable slowdowns between gcc and MSVC.

Not so easy to answer.
