Assuming that you're talking about MBytes/sec there is a chance
that your network link is using 100 MBit/sec full-duplex mode instead
of 1Gbit/sec. Try to do 'ifconfig | grep media' on the FreeBSD box
and watch for the speed regime specification.

Windows should report the interface speed too: unplug the cable, plug it
again and watch for the fancy popup on the taskbar. Or check the interface
properties box.
