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.

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