Although I do suspect the 3c589d (or its driver - zp ?) I get about 1MB in both directions on 10Base2 and about 9MB on a 100BaseTx. I am using Intel Etherexpress cards so I assume that it only can be the driver for your card or the card or your hardware. > do not handle ethernet collisions at all in a good way to be a possible > cause. I've never known ethernet ftp performance so bad as with the > equipment just mentioned. I have never seen better TCP performance than by using FreeBSD. So it really might be something depending on your hardware. I will have to setup a FreeBSD laptop with a 3c589 (:-() in about three weeks so maybe then I will have more infos. > > Darren -Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
