Continuous Throughput Test Results (Max Received Frame Rate at 100% of Line rate offered load)

Inferences

Theme: What is expected, What is unexpected,  

P2P:

  1. Only the smaller (64 and 128) packet sizes matter. For packets sizes above 128 the throughput performance remains similar.
  2. Scenarios 2 and 7 can be seen as the worst case scenarios with both the PMDs running on different NUMA than the NIC. As expected, the performance is consistently low for both scenarios-2 and 7.
  3. Interesting cases are Scenario-3 and Scenario-9.  Here a single pmd ends up serving both the NICs. This results in poorer performance than Scenario-2 and 7.
  4. Scenario 1, 6, and 8 can be seen as good cases where each of the NICs are served by single, separate PMDs.


PVP:

In these scenarios, we ensure there is always at least 1 PMD mapped to a NUMA to which a physical NIC is mapped to.
