2.3.1. L2 Ethernet Switching

Following sections include summary graphs of VPP Phy-to-Phy performance with L2 Ethernet switching, including NDR throughput (zero packet loss) and PDR throughput (<0.5% packet loss). Performance 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.

2.3.1.1. NDR Throughput

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