千兆局域网接收/传输速度不对等的问题cherbim3年前发布1040今天遇到了一个奇怪的问题,局域网内用 iperf 对另一台机器测速,发现单边差不多能跑 950M,反向确只能跑到 700 多 M,有没有大神能帮忙解惑。一台是 linux ，一台是 windows ，千兆组网以下是 iperf 输出：windows->linux[ ID] Interval Transfer Bandwidth[ 4] 0.00-1.00 sec 111 MBytes 929 Mbits/sec[ 4] 1.00-2.00 sec 112 MBytes 942 Mbits/sec[ 4] 2.00-3.00 sec 112 MBytes 942 Mbits/sec[ 4] 3.00-4.00 sec 112 MBytes 942 Mbits/sec[ 4] 4.00-5.00 sec 112 MBytes 942 Mbits/sec[ 4] 5.00-6.00 sec 112 MBytes 942 Mbits/sec[ 4] 6.00-7.00 sec 112 MBytes 941 Mbits/sec[ 4] 7.00-8.00 sec 112 MBytes 942 Mbits/sec[ 4] 8.00-9.00 sec 112 MBytes 941 Mbits/sec[ 4] 9.00-10.00 sec 112 MBytes 937 Mbits/sec[ ID] Interval Transfer Bandwidth[ 4] 0.00-10.00 sec 1.09 GBytes 940 Mbits/sec sender[ 4] 0.00-10.00 sec 1.09 GBytes 940 Mbits/sec receiverlinux->windows[ ID] Interval Transfer Bandwidth[ 4] 0.00-1.00 sec 88.2 MBytes 740 Mbits/sec[ 4] 1.00-2.00 sec 90.0 MBytes 755 Mbits/sec[ 4] 2.00-3.00 sec 90.6 MBytes 760 Mbits/sec[ 4] 3.00-4.00 sec 90.1 MBytes 756 Mbits/sec[ 4] 4.00-5.00 sec 89.3 MBytes 749 Mbits/sec[ 4] 5.00-6.00 sec 90.0 MBytes 755 Mbits/sec[ 4] 6.00-7.00 sec 90.5 MBytes 759 Mbits/sec[ 4] 7.00-8.00 sec 90.0 MBytes 755 Mbits/sec[ 4] 8.00-9.00 sec 88.8 MBytes 745 Mbits/sec[ 4] 9.00-10.00 sec 89.1 MBytes 748 Mbits/sec[ ID] Interval Transfer Bandwidth Retr[ 4] 0.00-10.00 sec 900 MBytes 755 Mbits/sec 0 sender[ 4] 0.00-10.00 sec 897 MBytes 752 Mbits/sec receiver
