The following reply was made to PR misc/34073; it has been noted by GNATS. From: "Dimitris sehh Michelinakis" <dimitris@michelinakis.gr> To: freebsd-gnats-submit@FreeBSD.org, pjah@hicom.net Cc: Subject: Re: misc/34073: 3com 3c980c runs "bursty" / freezes-unfreezes Date: Wed, 23 Oct 2002 11:51:29 +0200 This is a known problem with the 3Com driver. This bug is a duplicate of: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/18558 The problem is that receiving is dead slow, even though sending is running at full speed. The problem can be partialy fixed if you lower the receive buffers, but that won't eliminate it completely. (instead of getting 200kb/s you'll get 1mb/s etc). I'm running a 3Com 3c905-TX Fast Etherlink XL under fbsd 4.7-R, which is connected to a Netgear Switch, 100mbit full-duplex. -- Dimitris 'sehh' Michelinakis To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
