Yes it is. iperf doesn't test full duplex, it's one direction only (with one connection, run a server and a client on each side and you can test full duplex). You'll never get more than 100 Mb on a 100Mb link or 10 Mb on a 10 Mb link, even if it's full duplex, with a single iperf server and client. > > I'm able to get 93Mb to another machine on the network - acceptable, > given the cheap switch I have. > that's roughly as good as you're going to get on 100 Mb. > > I have two rl cards and one sis - sis0 is linked to my cable modem and > my LAN is to rl0. The RL NICs are both rather new, and both say they've > autonegotiated at 100Mb. rl's are known for poor performance, but should be better than that unless you're only running a 100-200 MHz machine or so. what duplex does it say? or does it not say? I'm still thinking duplex mismatch, though 20 something Mb is quite a bit for having a mismatch. You should be seeing: media: Ethernet autoselect (100baseTX <full-duplex>) in your ifconfig output. Exactly what are you seeing on that line? -cmb --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
