lan bandwidth issue

[silent slim]

This has gotta be a software issue... it seems logically impossible for
it to be otherwise.  I have my windows box running off a nat on my fbsd
box, it transmits to my isp at a max of about 160k down 70k up.
Transfering files between the two boxes can be done at a max of 1.6M down
and 130k up. Hense its physcially impossible for it to be a hardware
problem.  This is all quite annoying as both boxes are connected by
http://www.startech.com/ststore/itemdetail.cfm?tab=b&ProductID=ST100S&topbar=topbara.htm
10/100 nics and a 50' crossover cable.  Anyone have any ideas on what is
causing this issue and how it could possibly be resolved?

Here is the output from ifconfig on the bsd box:
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255

And here is the output from ipconfig /all on the the win box:
