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.
