For test cases that require DUT (VPP) to communicate with VM over vhost-user
interfaces, a VM is created on SUT1 and SUT2. DUT (VPP) test topology with VM
is shown in the figure below including applicable packet flow thru the VM

VPP Performance Tests Overview
------------------------------
-Performance tests are split into two main categories:
+Performance tests are split into the two main categories:
- Throughput discovery - discovery of packet forwarding rate using binary search
in accordance to RFC2544.
- - NDR - discovery of Non Drop Rate, zero packet loss.
- - PDR - discovery of Partial Drop Rate, with specified non-zero packet loss.
+ - NDR - discovery of Non Drop Rate packet throughput, at zero packet loss;
+ followed by packet one-way latency measurements at 10%, 50% and 100% of
+ discovered NDR throughput.
+ - PDR - discovery of Partial Drop Rate, with specified non-zero packet loss
+ currently set to 0.5%; followed by packet one-way latency measurements at
+ 100% of discovered PDR throughput.
- Throughput verification - verification of packet forwarding rate against
previously discovered throughput rate. These tests are currently done against
0.9 of reference NDR, with reference rates updated periodically.

+Execution of performance tests takes time, especially the throughput discovery
+tests. Due to limited HW testbed resources available within FD.io labs hosted
+by Linux Foundation, the number of tests for NICs other than X520 (a.k.a.

+testbed resources to grow, and will be adding complete set of performance
