L2 Ethernet Interface Loop
==========================
Following sections include summary graphs of DPDK Testpmd Phy-to-Phy performance
with L2 Ethernet Interface Loop, including NDR throughput (zero packet loss)
and PDR throughput (<0.5% packet loss). Performance 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.
Results are generated by multiple executions of the same CSIT
performance tests across three physical testbeds within LF FD.io labs.
To provide a descriptive summary view, Box-and-Whisker plots are used to
display variation in measured throughput values, without making any
assumptions of the underlying statistical distribution. For each plotted
test case, Box-and-Whisker plots show the quartiles (Min, 1st quartile
/ 25th percentile, 2nd quartile / 50th percentile / mean, 3rd quartile /
75th percentile, Max) across collected data set (data set size stated in
the note below). Outliers are plotted as individual points.
*Title of each graph* is a regex (regular expression) matching all
throughput test cases plotted on this graph, *X-axis labels* are indices
of individual test suites executed by csit-dpdk-perf-1704-all 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* lists the plotted test suites and their indices.
.. note::
Test results have been generated by FD.io test executor jobs
`csit-dpdk-perf-1704-all
<https://jenkins.fd.io/view/csit/job/csit-dpdk-perf-1704-all/>`_,
with Robot Framework result files csit-dpdk-perf-1704-all-<id>.zip
`archived here <../../_static/archive/>`_. Plotted data set size per
test case is equal to the number of job executions presented in this
report version: **4**.
