IPv4 Routed-Forwarding
======================
This section includes summary graphs of VPP Phy-to-Phy packet latency
with IPv4 Routed-Forwarding 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.
VPP packet latency in 1t1c setup (1thread, 1core) is presented in the graph below.
