I read that the Intel C++ compiler gives something like 25-50% performance boost to linux binaries over GCC. Something about how GCC is so platform independent that it doesn't really optimize very well on Intel. The Intel C++ compiler takes advantage of MMX, SSE, and SSE2 instructions (SSE2 only works on P4 procs, but Athlons can use MMX and regular SSE).

The license is very restrictive for the Intel compiler. Free for educational use only. Any chance of this profile appearing anytime soon?

I noticed an increase in speed with a simple "for" loop (to test)
(on a Pentium Pro 200)
imagine on a whole big program ...
This could be really interreting to try to compile some packages with it
