Most of the implementations I have seen for OVS-DPDK mean that the VM side would also use DPDK. Because even from a DPDK perspective at the compute level, the VM will become the bottleneck. 200k PPS with OVS-DPDK + non-DPDK VM is about what you get with OVS + OVSfirewall + non-DPDK VM.

Folks,
I have deployed openstack and configured OVS-DPDK on compute nodes for high performance networking. My workload is general purpose workload like running haproxy, mysql, apache and XMPP etc.
When I did load testing I found performance was average and after 200kpps packet rate I noticed packet drops. I heard and read that DPDK can handle millions of packets but in my case its not true. I am using virtio-net in guest vm which processes packets in the kernel so I believe my bottleneck is my guest VM.
I don't have any guest based DPDK applications like testpmd etc. does that mean OVS+DPDK isn't useful for my cloud? How do I take advantage of OVS+DPDK with general purpose workload?
Maybe I have the wrong understanding about DPDK so please help me :)
