hi, i've often been wondering how large the differences between compilers are. does anybody have or know of a comparison of C compiler .exe speeds for chess-relevant integer performance? e.g. crafty compiled with different compilers run on the same machine? i'm asking because a fellow checkers programmer has claimed the metroworks compiler (which i don't know myself) produces much (60%!) faster code than the microsoft compiler - and i'm kind of sceptic about that. in my experience, the MS compiler is a bit slower than the intel compiler, but not much (~10%); and it's a bit faster than GCC, but again not that much (again ~10%). i certainly always thought of it as a very good compiler. any numbers anyone? cheers martin
