Hmm, you must be mixing up me with someone else, since as far as I know, I haven't sent anyone anything related to ASM benchmarks, as I don't even know ASM well enough.

Why don't you want to use external libraries? The clock() in time.h is AWFULLY inaccurate(Running time for my plasmas were over 14 seconds, whereas it should have stopped right after 10 seconds were passed.) under heavy CPU load, thus there is no accurate way of measuring time.
