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 latency test cases, *X-axis labels* are indeces of csit-vpp-perf-1704 jobs
12 that created result output files used as data sources for the graph,
13 *Y-axis labels* are measured packet Latency [uSec] values, and the *graph
14 legend* identifes the plotted test suites.
18 Data sources for reported test results: i) FD.io test executor jobs
19 `csit-vpp-perf-1704-all
20 <https://jenkins.fd.io/view/csit/job/csit-vpp-perf-1704-all/>`_ ,
21 ii) archived FD.io jobs test result `output files
22 <../../_static/archive/>`_.
24 VPP packet latency - running in configuration of **one worker thread (1t) on one
25 physical core (1c)** - is presented in the figure below.
