IPv4 Routed-Forwarding
======================
Following sections include summary graphs ofL3FWD Phy-to-Phy performance with
packet routed forwarding, including NDR throughput (zero packet loss)
and PDR throughput (<0.5% packet loss). Performance is reported for L3FWD
running in multiple configurations of L3FWD pmd thread(s), a.k.a. L3FWD
data plane thread(s), and their physical CPU core(s) placement.
NDR Throughput
~~~~~~~~~~~~~~
Testpmd NDR 64B packet throughput in 1t1c setup (1thread, 1core) is presented
in the graph below.
