4 This section provides a summary of VPP Phy-to-Phy L2 Ethernet switching
5 performance illustrating packet latency measured at 50% of discovered NDR
6 throughput rate. Latency is reported for VPP running in multiple
7 configurations of VPP worker thread(s), a.k.a. VPP data plane thread (s), and
8 their physical CPU core(s) placement.
10 Title of each graph is a regex (regular expression) matching all plotted
11 test case throughput measurements.
15 Data sources for reported test results: i) FD.io test executor jobs
16 `csit-vpp-perf-1701-all
17 <https://jenkins.fd.io/view/csit/job/csit-vpp-perf-1701-all/>`_ and
18 `csit-vpp-perf-1701-long
19 <https://jenkins.fd.io/view/csit/job/csit-vpp-perf-1701-long/>`_
20 , ii) archived FD.io jobs test result `output files
21 <../../_static/archive/>`_.
23 VPP packet latency - running in configuration of **one worker thread (1t) on one
24 physical core (1c)** - is presented in the figure below.
