4 This section includes summary graphs of VPP Phy-to-Phy packet latency
5 with IPv4 Overlay Tunnels measured at 50% of discovered NDR throughput
6 rate. Latency is reported for VPP running in multiple configurations of
7 VPP worker thread(s), a.k.a. VPP data plane thread(s), and their
8 physical CPU core(s) placement.
10 VPP packet latency in 1t1c setup (1thread, 1core) is presented in the graph below.
