Im sorry, i mean to say receiving, not sending. I did try adjusting this,
but it made no difference. Just to recap:

netio server running windows xp, connecting from fbsd:

TCP/IP connection established.
Packet size  1 KByte:   41103 KByte/s
Packet size  2 KByte:   39601 KByte/s
Packet size  4 KByte:   43463 KByte/s
Packet size  8 KByte:   43734 KByte/s
Packet size 16 KByte:   43719 KByte/s
Packet size 32 KByte:   43656 KByte/s

netio server running on fbsd, connecting from windows xp:

TCP/IP connection established.
Packet size  1 KByte:   19347 KByte/s
Packet size  2 KByte:   21056 KByte/s
Packet size  4 KByte:   22845 KByte/s
Packet size  8 KByte:   23445 KByte/s
Packet size 16 KByte:   25082 KByte/s
Packet size 32 KByte:   25294 KByte/s

So as we can see, i am getting nearly half the performance when sending to
the fbsd server. I get simillar results when substituting the windows
server with a fbsd 5.4 server, and using 100mbit cards on both.
