Pretty much to get the best speed increase you need to do profiling. Install MSVC with the IntelC 5 compiler... use these switch's.. "/G6 -O3 -Qipo -Qunroll -QxiK -Qprof_genx -Qprof_dir c:\opt" Compile, run your program.. after it generates the profiling information recompile w/ that same string except replace -Qprof_genx with -Qprof_use You'll need to tinker with various settings, sometimes -QxK is faster, sometimes -QxiM, etc.. it's all in the documentation..
