4 This section provides a summary of VPP Phy-to-Phy IPv4 Overlay Tunnels
\r
5 performance illustrating packet latency measured at 50% of discovered NDR
\r
6 throughput rate. Latency is reported for VPP running in multiple
\r
7 configurations of VPP worker thread(s), a.k.a. VPP data plane thread (s), and
\r
8 their physical CPU core(s) placement.
\r
10 Title of each graph is a regex (regular expression) matching all plotted
\r
11 test case throughput measurements.
\r
15 Data sources for reported test results: i) FD.io test executor jobs

22 VPP packet latency - running in configuration of **one worker thread (1t) on one
\r
