No, not really. The performance of samba on freebsd still sucks. I have 
a gigabit link between my samba server and windows xp workstation, both 
use the intel em card. The fastest i can download from the freebsd 
server is 15.946 MB/s, fastest upload to is 13.594 MB/s. Thats pretty 
poor for a gigabit link. However, 9MB/s on your link is not bad at all, 
one has to consider the protocol overhead.

This feature limited the speed of LANs, however recent code has aimed to 
fix that, but i don't think its in 6.0. I used a recent -CURRENT for the 
tests, you should consider updating to -STABLE.
