VM vhost Connections ==================== This section provides a summary of VPP Phy-to-VM-to-Phy VM vhost-user performance illustrating packet latency measured at 50% of discovered NDR throughput rate. Latency is reported for VPP running in multiple configurations of VPP worker thread(s), a.k.a. VPP data plane thread (s), and their physical CPU core(s) placement. Title of each graph is a regex (regular expression) matching all plotted test case throughput measurements. .. note:: Data sources for reported test results: i) FD.io test executor jobs `csit-vpp-perf-1701-all `_ and `csit-vpp-perf-1701-long `_ , ii) archived FD.io jobs test result `output files <../../_static/archive/>`_. VPP 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.
