After CloudNetEngine vswitch technical preview is launched, we received quite a few queries on vswitches performance comparison, but we cannot simply give a test result on our platform because performance varies on different H/Ws and different workloads, and that's why we encourage you to try the evaluation package to get real data on your setup.
Anyway, we share a little more performance data on our H/W which is a comparison among native kernel OVS/OVS-DPDK/CNE vswitch under the most common workload: concurrent bi-directional TCP traffics cross hosts, and hope you can have a rough idea. http://www.cloudnetengine.com/weblog/2015/07/22/vswitches-performance-comparison/ Thanks, Jun
