3.3.2. 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.

3.3.2.1. NDR Throughput

Testpmd NDR 64B packet throughput in 1t1c setup (1thread, 1core) is presented in the graph below.

3.3.2.2. PDR Throughput

L3FWD PDR 64B packet throughput in 1t1c setup (1thread, 1core) is presented in the graph below. PDR measured for 0.5% packet loss ratio.
