[ovs-discuss] OVS internal port performance is not good when used with OVS DPDK

Hi all,

I tried below test cases to compare the performance of OVS/OVS
DPDK+Internal port.

*Topology*:

​*Test results:*


​

 Now I have following 2 questions.

1.  Does the test result is normal?  If it is not normal, why?
2.  When ovs internal port is used with OVS DPDK, the max packet size sent
by DPDK PKTGEN
     can not be larger than 978 bytes. Otherwise the traffic will be
blocked. Does anyone know the
     reason?

It will be great if someone from the list could give the answers and clues.

Thanks.
Leo
