IPv4 Overlay Tunnels
====================
-This section provides a summary of VPP Phy-to-Phy IPv4 Overlay Tunnels
-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.
+This section includes summary graphs of VPP Phy-to-Phy packet latency
+with IPv4 Overlay Tunnels 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.

-VPP packet latency - running in configuration of **one worker thread (1t) on one
-physical core (1c)** - is presented in the figure below.
+VPP packet latency in 1t1c setup (1thread, 1core) is presented in the graph below.
