标题: 各种模式虚拟化的网络性能对比测试

dpdk+ovs 与 物理机 与 sriov(pci passthrough) 纯粹的linux bridge的性能对比

CPU E5-2680V2 2.8G，网卡 ixgbe intel 82599。


[attach]120986[/attach]


测试方法：路由转发

结构为：A------R------B

实际上R有两块网卡，有4个方向的数据包，本测试只取其中之一，同时使用了LINUX的路由功能做测试，所以不做为各种技术的基准测试参考，只是一个相对值。

A做netserver，R替换为以上各种模式的机器，B做netperf的客户端

分别使用netperf做20、40、80并发并绑定CPU进行TCP_RR测试。
