Latency is reported for Testpmd running in multiple +configurations of Testpmd pmd thread(s), a.k.a. Testpmd data plane +thread(s), and their physical CPU core(s) placement. + +Results are generated from a single execution of CSIT NDR discovery +test. Box plots are used to show the Minimum, Average and Maximum packet +latency per test. + +*Title of each graph* is a regex (regular expression) matching all +throughput test cases plotted on this graph, *X-axis labels* are indices +of individual test suites executed by csit-dpdk-perf-1704-all job that +created result output file used as data source for the graph, *Y-axis +labels* are measured packet Latency [uSec] values, and the *Graph +legend* lists the plotted test suites and their indices. Latency is +reported for concurrent symmetric bi-directional flows, separately for +each direction: i) West-to-East: TGint1-to-SUT1-to-SUT2-to-TGint2, and +ii) East-to-West: TGint2-to-SUT2-to-SUT1-to-TGint1. + +.. note:: + + Test results have been generated by FD.io test executor jobs + `csit-dpdk-perf-1704-all + `_, + with Robot Framework result files csit-dpdk-perf-1704-all-.zip + `archived here <../../_static/archive/>`_ + +Testpmd packet latency - running in configuration of **one worker thread (1t) on one +physical core (1c)** - is presented in the figure below. + +.. raw:: html + + + +*Figure 1.
