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.
That's supposed to be in 6.1, but still the speed still is sub par :

Modified files:
sys/netinet tcp_input.c tcp_subr.c tcp_timer.h
tcp_var.h
Log:
Have TCP Inflight disable itself if the RTT is below a certain
threshold. Inflight doesn't make sense on a LAN as it has
trouble figuring out the maximal bandwidth because of the coarse
tick granularity.
The sysctl net.inet.tcp.inflight.rttthresh specifies the threshold
in milliseconds below which inflight will disengage. It defaults
to 10ms.
