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.
