I tried this once upon a time. I found it more difficult than I
expected. Typical hardware - especially hard drives - cannot keep up to
a gigabit link. I used an FTP server running from a RAM disk. Even
then, the Atom CPU in the server had a hard time sustaining more than
60MB/sec of transfer.
In the end I concluded that I was testing the limits of my CPU and disk
subsystem more than any network hardware.
It is entirely possible your Windows client can write transferred files
to disk at only 25MB/s (which is pretty good).
