   4 This section includes summary graphs of VPP Phy-to-VM(s)-to-Phy packet
   5 latency with with VM virtio and VPP vhost-user virtual interfaces
   6 measured at 50% of discovered NDR throughput rate. Latency is reported
   7 for VPP running in multiple configurations of VPP worker thread(s),
   8 a.k.a. VPP data plane thread(s), and their physical CPU core(s)
   9 placement.
