[mingw - C/C++] gcc 3.2.3 performance: windows VS linux

Hi, I have got a question on the performance
comparison between windows and linux. Using
the same machine, should I expect that gcc 3.2.3
generate executables that run with similar, if not idential, performance on
linux and windows XP?
Can someone enlighten me on this?
also should I expect that gcc 3.2.3 to be faster than gcc 2.9.6??
Thanks a lot,
Jimmy Zhang

Well, given the significant differences between Windows XP and Linux,
and even the differences in the way the libraries are implemented, I
wouldn't be surprised if you saw differences.

I can't comment much on the differences you'd find between gcc 3.2.3 and
gcc 2.9.6, but I'm not sure why you'd expect it to be faster.  Maybe
better, with more options and better support for various things, but
again, it's really going to depend on what you're doing and how you're
doing it.
