+===
+
+This section includes summary graphs of VPP Phy-to-VM(s)-to-Phy packet
+latency with with VM virtio and VPP vhost-user virtual interfaces
+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.
+
+CSIT source code for the test cases used for plots can be found in
+`CSIT git repository <https://git.fd.io/csit/tree/tests/vpp/perf/vts?h=rls1807>`_.
