Nope, that's not it. I get the same behavior from an Intel PRO/1000. And if that were the problem, I'd see it no matter what hosts I connect to, but if I make the other end a FreeBSD 6.1 box, I get a near-full pipe in both direction. > They're fine for light home use (and well priced for that).

I was using the intel until I needed to bridge it, and the rl bridging code worked where the em code didn't. http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information.
