Hi everybody

I would like to know what are the best compiler/switches to compile code
for a pentium II ?

Compiled with GCC 2.8.1 my program runs at 25 fps.
With PGCC and the same switches (-mpentium -O6) it drops at 15 !!!

Does GCC 2.8.1 produce more "Pentium II friendly" code ?
Can Egcs help ?

I hope my english isn't too difficult to understand.

I use Allegro for my program. The library is compiled with the same
compiler with pentium optimizations on.

Can anyone help ?
