运行在1千兆以下的10G网卡

我在两台服务器中安装了10个千兆光纤卡，但是当我testing吞吐量时，它们的运行速度只有大约600Mbps左右：

$ scp random.1G rcm2:/tmp random.1G 100% 1024MB 73.1MB/s 00:14

我的路线看起来正确。 networking驱动程序和硬件似乎设置正确。

有人可以告诉我，我应该在哪里看？

以下是更多信息：

路由

172.16.157.34

 $ ip route get 172.16.157.35 172.16.157.35 dev eth1 src 172.16.157.34

172.16.157.35

 $ ip route get 172.16.157.34 172.16.157.34 dev eth2 src 172.16.157.35

硬件/使用ifconfig

172.16.157.34

 $ ifconfig ... eth2 Link encap:Ethernet HWaddr 90:e2:ba:38:aa:ee inet addr:172.16.157.34 Bcast:172.16.157.63 Mask:255.255.255.224 ... $ lshw -class network ... description: Ethernet interface product: 82599EB 10-Gigabit SFI/SFP+ Network Connection ... serial: 90:e2:ba:38:aa:ee ...

172.16.157.35

 $ ifconfig ... eth1 Link encap:Ethernet HWaddr 90:E2:BA:38:AA:82 inet addr:172.16.157.35 Bcast:172.16.157.63 Mask:255.255.255.224 ... $ lshw -class network ... description: Ethernet interface product: 82599EB 10-Gigabit SFI/SFP+ Network Connection ... serial: 90:e2:ba:38:aa:82 ...

scp在处理数据时有很大的开销。像nc这样的更薄的东西将为您提供更好的吞吐量和更真实的服务器和networking物理functiontesting。

另外，确保你的瓶颈不存在于其他地方像你的磁盘。使用iperf或类似的东西testing非磁盘吞吐量。
