   4 Following sections provide a summary of VPP Phy-to-VM-to-Phy VM vhost-user
   5 performance illustrating NDR throughput (zero packet loss) and PDR throughput
   6 (<0.5% packet loss). Performance 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.
   9
  10 *Title of each graph* is a regex (regular expression) matching all plotted
  11 throughput 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 Packets Per Second [pps] values, and the *graph
  14 legend* identifes the plotted test suites.

  16 .. note::

  18     Data sources for reported test results: i) FD.io test executor jobs
