Intels website states that 1.7 is for FreeBSD 4.x and that it is no longer maintained. The 2.x is for FreeBSD 5.3+, and is maintained. I think this is a good chance to bring it up to date. >> Seems like i am getting half the performance when sending to the fbsd >> box.

Oddly enough, i ran the same benchmark between that same server and another freebsd box. However this time i ran it on 100mbit cards. A rl, and an fxp on the original server (wich has the em card also). I got the same results! Sending to the server gave me 11MB/s, but sending from it gave me about 7-8MB/s. There may be a problem in -CURRENT.
