Thanks for the reply! Maybe I should have been more clear.
My setup looks like this:
internet - em1(server box) em0 - windoze desktop.
The internet(em1) 100mbit seems to do fine, even better than
before, I get about 11mb/s with rtorrent(uploading). It's the
internal gbit connection that's weird with ftp. It not as fast nor
as smooth as it was before I did the "tuning". I doesn't have
any trouble running ftping at 30mb/s after the tuning so it is
definately capabel of delivering 100mbit?
$ifconfig -a

If you had something else in mind, let me know. When I transferred large
files I sometimes got about 600 packages dropped by kernel. That
can't be good. Also it seemed that I got a lot of ack packages, don't
know if that's normal.
