VM vhost Connections ==================== Following sections include summary graphs of VPP Phy-to-VM(s)-to-Phy performance with VM virtio and VPP vhost-user virtual interfaces, 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. NDR Throughput ~~~~~~~~~~~~~~ VPP NDR 64B packet throughput in 1t1c setup (1thread, 1core) is presented in the graph below. .. raw:: html .. raw:: latex \begin{figure}[H] \centering \graphicspath{{../_build/_static/vpp/}} \includegraphics[clip, trim=0cm 8cm 5cm 0cm, width=0.70\textwidth]{64B-1t1c-vhost-sel1-ndrdisc} \label{fig:64B-1t1c-vhost-sel1-ndrdisc} \end{figure} *Figure 1a.
