hi, I think you should be able to hit line rate for a phy-phy test with 1 PMD depending on what processor you are using. I would stick to 1 PMD and 1 rxq for debugging - increasing may help mitigate any issue, but will make it harder to debug. What rules are you installing? also what processor are you using? Is the PMD getting ~100% of a core or is there something else running - you can check with top -H > > We also re-tested our setup with OVS master (from github) and DPDK 2.1 > and found no difference to the results described in my first posting. > _______________________________________________ > discuss mailing list > discuss@openvswitch.org > http://openvswitch.org/mailman/listinfo/discuss _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
