   1 IPv4 Routed-Forwarding
   2 ======================
   3
   4 This section includes summary graphs of VPP Phy-to-Phy packet latency
   5 with IPv4 Routed-Forwarding 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.
