IPv4 Routed-Forwarding
======================
This section provides a summary of VPP Phy-to-Phy IPv4 Routed-Forwarding
performance illustrating packet latency measured at 50% of discovered NDR
throughput rate. Latency is reported for VPP running in multiple
configurations of VPP worker thread(s), a.k.a. VPP data plane thread (s), and
their physical CPU core(s) placement.
*Title of each graph* is a regex (regular expression) matching all plotted
latency test cases, *X-axis labels* are indeces of csit-vpp-perf-1704 jobs
that created result output files used as data sources for the graph,
*Y-axis labels* are measured packet Latency [uSec] values, and the *graph
legend* identifes the plotted test suites.
.. note::
Data sources for reported test results: i) FD.io test executor jobs
`csit-vpp-perf-1704-all
`_ ,
ii) archived FD.io jobs test result `output files
<../../_static/archive/>`_.
VPP packet latency - running in configuration of **one worker thread (1t) on one
physical core (1c)** - is presented in the figure below.
