Asymmetric ethernet throughput?

Does disabling net.inet.tcp.inflight.enable make any difference? I've
noticed strange transfer speed differences between a samba server on
freebsd 6.1 and OS 10.4.6 clients and Windows.
With these set in /etc/sysctl.conf, I can get reasonable speeds on both
the macs and windows box.
I also needed to set these in /usr/local/etc/smb.conf
socket options = TCP_NODELAY SO_SNDBUF=8576
use sendfile = yes
I've also experimented with other settings like lowering the quality of
the timer with kern.timecounter.hardware=TSC which seemed to increase
throughput in some cases but not others.
