    I don't think this is a "new" Pentium bug. The Pentium (all known classes)
    have absimal performance compared to the '486 when using the "built-in"
    macro instructions such as rep movsb,movsw, scansb,scansw, etc. Also the
    "loop" instruction is slower than dec ecx; jnz;.. These are "known"
    performance problems that seemed to occur when the Pentium went RISC"y".

    I read the web page and don't see anything new, just new hype.

    Cheers,
