L2 Ethernet Looping
===================
Following sections provide a summary of VPP Phy-to-Phy L2 Ethernet Looping
performance illustrating NDR throughput (zero packet loss) and PDR throughput
(<0.5% packet loss). Performance is reported for Testpmd running in multiple
Testpmd worker thread (a.k.a. VPP data plane thread) and physical CPU core
configurations.
*Title of each graph* is a regex (regular expression) matching all plotted
throughput test cases, *X-axis labels* are indeces of csit-dpdk-perf-1704 jobs
that created result output files used as data sources for the graph,
*Y-axis labels* are measured Packets Per Second [pps] values, and the *graph
legend* identifes the plotted test suites.
.. note::
Sources of test results data: i) FD.io executor jobs `csit-dpdk-perf-1704-all
<https://jenkins.fd.io/view/csit/job/csit-dpdk-perf-1704-all/>`_ ,
ii) FD.io jobs archieved result files.
NDR Throughput
~~~~~~~~~~~~~~
NDR throughput of Testpmd - running in configuration of **one worker thread
(1t) on one physical core (1c)** - is presented in the figure below.

CSIT test cases used to generate results presented above can be found in CSIT
git repository by filtering with specified regex as follows:
.. code-block:: bash

NDR throughput of Testpmd - running in configuration of **two worker threads
(2t) on two physical cores (2c)** - is presented in the figure below.
