I just tried your patch, but unfortunately it does not seem to affect my problem, the speeds are identical. I am still getting half the performance when sending out. The fact that this also occurs using another machine and a different card, leads me to belive something is broken in -CURRENT.
net.inet.tcp.sendspace=65536 and try again.
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.
You surely must have meant 1000 Mbit cards. These numbers exceed the theoretical throughput of 100 Mbit networking (12500 KBytes/s).
Do the numbers differ significantly if you try this test between your CURRENT machine and say, a FreeBSD 4.x or Linux 2.6 machine?
