Unless you're speaking of the MMX instructions (which compete with the FPU because the registers are shared between the two for most processors), I don't think so. My K6 has no special instructions and is still 3 times faster under W95 for MP3 encoding. Even the MMX instructions can't explain a 3x difference IMHO. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 4.0-CURRENT #70: Sat Feb 27 09:43:08 CET 1999 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
