4 This section includes summary graphs of L3FWD Phy-to-Phy performance with packet
5 routed forwarding measured at 50% of discovered NDR throughput rate. Latency is
6 reported for L3FWD running in multiple configurations of L3FWD pmd thread(s),
7 a.k.a. L3FWD data plane thread(s), and their physical CPU core(s) placement.
9 L3FWD packet latency - running in configuration of **one worker thread (1t) on one
10 physical core (1c)** - is presented in the figure below.
