hi
I have meet a performance problem about ovs-dpdk.
test with netperf. when test with tcpstream mode,it works good.but in tcp_RR and tcp_CRR mode,it works not good.
test result:
[root at node-4 ~]# for i in `seq 43 47`; do ip netns exec qrouter-0cea5044-82f1-4ee7-a290-17c528aacc9c netperf -t TCP_RR -H 100.64.8.$i -l 10  & done
