4 This section provides a summary of VPP Phy-to-Phy IPv6 Overlay Tunnels
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

23 VPP packet latency - running in configuration of **one worker thread (1t) on one
24 physical core (1c)** - is presented in the figure below.
