1 L2 Ethernet Interface Loop
2 ==========================
4 Following sections include summary graphs of DPDK Testpmd Phy-to-Phy performance
5 with L2 Ethernet Interface Loop, including NDR throughput (zero packet loss)
6 and PDR throughput (<0.5% packet loss). Performance is reported for Testpmd
7 running in multiple configurations of Testpmd pmd thread(s), a.k.a. Testpmd
8 data plane thread(s), and their physical CPU core(s) placement.
10 Results are generated by multiple executions of the same CSIT tests.
11 In order to display variation in measured throughput values, Box-and-
12 whisker plots are used to show their quartiles (Min, 1st quartile / 25th
13 percentile, 2nd quartile / 50th percentile / mean, 3rd quartile / 75th
14 percentile, Max). Outliers are plotted as individual points.
16 *Title of each graph* is a regex (regular expression) matching all
17 throughput test cases plotted on this graph, *X-axis labels* are indices
18 of individual test suites executed by csit-dpdk-perf-1704-all jobs that
19 created result output files used as data sources for the graph, *Y-axis
20 labels* are measured Packets Per Second [pps] values, and the *Graph
21 legend* lists the plotted test suites and their indices.
25 Test results have been generated by FD.io test executor jobs
