In the first case, does your hub/switch agree that the link is in 100Mbit full duplex mode? Ditto for the Windows machine -- there's probbly an Intel control panel applet that will tell you what mode the EtherJet is in. For a direct cable connection you need to make sure that both cards are in the same mode. Disagreement over duplex modes seems to be the commonest cause of this kind of problem. > I'm using psFTP to transfer files which I think uses > ssh, could this be the > problem?

It's unlikely that the overhead of ssh is slowing things down *that* much. I find that the easiest way to moves files between my Wndows and BSD machines is to run Samba on the BSD boxen.
