From: Nick Christenson <n...@gangofone.com> To: bug-follo...@freebsd.org, vn...@vnovy.net Cc: Subject: Re: kern/121257: [tcp] TSO + natd -> slow outgoing tcp traffic Date: Sat, 30 Oct 2010 14:03:13 -0700 (PDT) I notice that not much has been done on this bug in the last couple of years, so here's a bump. I have reproduced this bug on an amd64 machine running FreeBSD 7.3-RELEASE-p3 with network cards using the msk driver. I'm running natd and pf. I'm not the only one who has encountered this. Other references to what looks like the same problem: http://lists.freebsd.org/pipermail/freebsd-net/2010-July/025731.html http://forums.freebsd.org/showthread.php?t=13900 http://osdir.com/ml/freebsd.bugs/2002-03/msg00051.html http://unix.derkeiler.com/Mailing-Lists/FreeBSD/questions/2010-01/msg00674.html http://comments.gmane.org/gmane.os.freebsd.current/127669 (subject "significantly slow IPFW + NATD + amd64) Many of these don't include resolutions, so if this can't be fixed, at least publicizing the work around would seem to be well advised. It sounds from the bug like the developers have a good handle on the problem, but if I can do anything to help test, let me know. -- Nick Christenson n...@gangofone.com _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
