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 plotted
test cases.
.. note::
Sources of test results data: i) FD.io executor jobs `csit-dpdk-perf-1701-all
`_ and
`csit-dpdk-perf-1701-long
`_, 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.
