I compiled a program under Turbo C++ 16bit which used lots of
unsigned long multiplications and such, and was very pleased
when it ran twice as fast (I did some time trials) when compiled
with DJGPP. Running under QEMM however I found it was a bit slow,
and it performed a little better from a Win95 shell. But when I
compiled the same program on a Linux box, it went twice as fast
yet again! Same processor (pentium 100) on both systems...
.... also the linux box had a bunch of other processes that it was
dealing with, news and web servers, email, and of course the
users that were logged in at the time. All in all a 4times speed
increase from the original Turbo C++ compilation.
