The last performance test was made on current hardware.
It was mono directional perf test with one DPDK port.
The results of the mono directional tests:
3 runs.
Stable result over all runs.
Mpps: 3.063646
Frame loss (0, 0.00000000%)
Hi,
Currently, OSP moved to work with OVS2.6,
I've verified the performance using openvswitch-2.6.1-10.git20161206.el7fdp.x86_64
And achieved 3.576437.
Thanks.

Description of problem: OSPD 10 + OVS DPDK two ports (bidirectional) performance tests. OVS + DPDK two ports performance tests show unstable results. Version-Release number of selected component (if applicable): RHOS 10 Product version: 10 Product core version: 10 Product core build: 2016-10-21.3 openvswitch-2.5.0-14.git20160727.el7fdb.x86_64 tuned-2.7.1-4.el7fdb.noarch How reproducible: Run back to back performance test with moongen. Steps to Reproduce: 1. Deploy RHOS 10 OVS DPDK environment with two DPDK ports. 2. Connect Compute node back to back with Moongen. 3. Run performance tests. Actual results: Three runs were performed.
