Testing the Performance of 4 PMDs

4.2.1

Test the packet rate of four forwarding cores on the server host.

See Figure 1.

See Building a Test Environment.

1. Start the OVS service.

   1	service openvswitch start

2. Set the boot parameters.

   1	ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true other_config:dpdk-socket-mem="4096" other_config:dpdk-lcore-mask="0x1F" other_config:pmd-cpu-mask="0x1E"

3. Restart the OVS service.

   1	service openvswitch restart

4. Set the VM queue.

   1	virsh edit VM1

   Change the value marked in the following figure to 8.

   

   Modify VM 1 to VM 8 one by one.

5. Modify the networking script.
   1. Change PCI addresses of network ports based on 4. You need to configure them only once.
   2. Change the queue number of network ports. Change the values marked in the following figure to 8.

   

6. Perform the test based on Testing the Performance of One PMD.

The difference of multiple test results for the same CPU does not exceed 10%.
