Testpmd
=======

This section includes summary graphs of Testpmd Phy-to-Phy packet
latency with L2 Ethernet Interface Loop measured at 50% of discovered
NDR throughput rate. Latency is reported for Testpmd running in multiple
configurations of Testpmd pmd thread(s), a.k.a. Testpmd data plane
thread(s), and their physical CPU core(s) placement.

CSIT source code for the test cases used for plots can be found in
`CSIT git repository <https://git.fd.io/csit/tree/tests/dpdk/perf?h=rls1807>`_.
