Hi David S. Miller and maintainers: I use the 4.1.16 kernel to build my system and use the iperf to test the netstat, it looks very strange that the client shows:
netstat -at | grep 10.175.112.105 tcp 0 0 10.175.112.191:ssh 10.175.112.105:58400 ESTABLISHED tcp 0 0 10.175.112.191:33230 10.175.112.105:5001 TIME_WAIT tcp 0 4202096 10.175.112.191:33231 10.175.112.105:5001 ESTABLISHED tcp 0 0 10.175.112.191:ssh 10.175.112.105:58335 ESTABLISHED and the speed is: [ 3] 0.0-300.0 sec 32.5 GBytes 929 Mbits/sec It looks like that the speed is fine, But I don't know why the Send-Q has so many buffers, the tcp_wmem is big enough and I couldn't found any difference, did I miss something or is there something wrong for the TCP config? Thanks for any suggestion. Ding
