   1 VM vhost Connections
   2 ====================
   3
   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.
  10
  11 Results are generated from a single execution of CSIT NDR discovery
  12 test. Box plots are used to show the Minimum, Average and Maximum packet
  13 latency per test.
  14
  15 *Title of each graph* is a regex (regular expression) matching all
  16 throughput test cases plotted on this graph, *X-axis labels* are indices
  17 of individual test suites executed by csit-vpp-perf-1704-all job that
  18 created result output file used as data source for the graph, *Y-axis
  19 labels* are measured packet Latency [uSec] values, and the *Graph
  20 legend* lists the plotted test suites and their indices. Latency is
  21 reported for concurrent symmetric bi-directional flows, separately for
  22 each direction: i) West-to-East: TGint1-to-SUT1-to-SUT2-to-TGint2, and
  23 ii) East-to-West: TGint2-to-SUT2-to-SUT1-to-TGint1.
