    Hi
    I am using Perf to test BitMagic, but i didn't any improvment with BMSSE2OPT defined.

    here is my platform:
    Intel p4 CPU 3G
    2G mem
    windows xp s3
    vs2008

    any idea?

    if BMCOUNTOPT is defined. the performance has significant improvement, BUT it looks like this is a alrightm change, not caused by SSE2. since count is cached!

    right?
