And an athlon64 3500+ (2.2GHz) runs bzip2 5x faster than a 2.8GHz Pentium 4. The pentium 4 HATES branch heavy code when the branch prediction fails to work (which essentially by definition it has to on compression and other optimizing/solving problems). It might have been a good design for multimedia streaming operations, but it really sucks at many general purpose tasks. I never did like the pentium 4 even from day 1. -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
