- Only the smaller (64 and 128) packet sizes matter. For packets sizes above 128 the throughput performance remains similar.
- Scenarios 2 and 7 can be seen as the worst case scenarios with both the PMDs PMD-cores running on different NUMA than the NIC. As expected, the performance is consistently low for both scenarios-2 and 7.
- Interesting cases are Scenario-3 and Scenario-9. Here a single pmd-core ends up serving both the NICs. This results in poorer performance than Scenario-2 and 7.
- Scenario 1, 6, and 8 can be seen as good cases where each of the NICs are served by single, separate PMDsPMD-cores.
- When one NIC is served by pmd-core on the same NUMA, whereas the other NIC is served by pmd-core on a different NUMA - Scenarios 4 and 5 - can be seen as average cases with lower performance than 1, 6 and 8 - but not as low as 3, 9, 2, and 7.
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.
