4 This section provides a summary of VPP Phy-to-VM-to-Phy VM vhost-user
5 performance illustrating packet latency measured at 50% of discovered NDR
6 throughput rate. Latency is reported for VPP running in multiple
7 configurations of VPP worker thread(s), a.k.a. VPP data plane thread (s), and
8 their physical CPU core(s) placement.
9
10 *Title of each graph* is a regex (regular expression) matching all plotted
11 latency test cases, *X-axis labels* are indeces of csit-vpp-perf-1704 jobs
12 that created result output files used as data sources for the graph,
13 *Y-axis labels* are measured packet Latency [uSec] values, and the *graph
14 legend* identifes the plotted test suites.
