I've done some benchmarking recently, not to compare compilers (well,
I've also noticed the speed decrease at higher optimization levels
with egcs), but to compare operating systems.  I don't know how MS
managed to do this, but the VMM implementation of Windows 95 is really
broken. (Look at http://www1.stuttgart.netsurf.de/~fw/hint.html)  Of
course, we all knew this already...
