For 50% CPU, yes, that's about right. You can do about 11MB/sec on a typical P5 system (100% CPU). It looks like the K6 is throttling the speed potential or the test you're doing is slowing it down (perhaps involving file I/O?). -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org Creator of high-performance Internet servers - http://www.terasolutions.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
