This is with standard compression/decompression and idea encryption/decryption. Since this has to run both ends, my K6-2 350 is really doing 4Mb/s or higher (take into account lo0 overhead.) I'd expect a P6 (II, whatever) running at at 450 to beat that, by around 15%. > > > -Matt > Matthew Dillon > <dillon@backplane.com> Brian Fundakowski Feldman _ __ ___ ____ ___ ___ ___ green@FreeBSD.org _ __ ___ | _ ) __| \ FreeBSD: The Power to Serve! _ __ | _ \._ \ |) | http://www.FreeBSD.org/ _ |___/___/___/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
