I did a simple benchmark test by using qperf, to my surprise, sockeplane did no play well.

SocketPlane container to container:
tcp_bw:
bw = 6.7 MB/sec
tcp_lat:
latency = 290 us

Host to host:
tcp_bw:
bw = 11.7 MB/sec
tcp_lat:
latency = 141 us

It's not as good as flannel+vxlan which is 70%-80% of "native", according to my test.

Does anyone has historical benchmark test results to share & comparison with flannel?
