Reading the pdf file, it > seems forwarding performance on 6 and 7 is still much lower than > RELENG_4 ? is that correct ? Haven't tested RELENG_4 performance in a controlled environment and thus can't answer the question directly. However using fastforward on 6 and 7 is key to good performance. Without it you're stuck at some 150-200kpps, perhaps 300kpps. With it you get to 500-800kpps. -- Andre > ---Mike >> You can find a summary of all my tests and the source code at the >> following address: >> http://www.netasq.com/opensource/pollng-rev1-freebsd.tgz >> >> Feel free to ask more detailed information if necessary and report >> any bugs / comments. >> >> Fabien >> >> >> _______________________________________________ >> freebsd-net@freebsd.org mailing list >> http://lists.freebsd.org/mailman/listinfo/freebsd-net >> To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" > > -------------------------------------------------------- > Mike Tancsa, Sentex communications http://www.sentex.net > Providing Internet Access since 1994 > mike@sentex.net, (http://www.tancsa.com) > _______________________________________________ > freebsd-net@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" > >
