+VPP HTTP Server Performance Results
+===================================
+
+Plotted results are generated by multiple executions of the same CSIT
+performance tests across three physical testbeds within LF FD.io labs.
+To provide a descriptive summary view, Box-and-Whisker plots are used to
+display variation in measured performance values, without making any
+assumptions of the underlying statistical distribution.
+
+For each plotted test case, Box-and-Whisker plots show the quartiles
+(Min, 1st quartile / 25th percentile, 2nd quartile / 50th percentile /
+mean, 3rd quartile / 75th percentile, Max) across collected data set
+(data set size stated in the note below). Outliers are plotted as
+individual points. Min and max values are plotted as bottom and top
+Whiskers respectively. 2nd and 3rd quartiles are plotted as bottom and
+top edge of the box. If multiple samples match only two values, and all
+samples fall between them, then no whiskers are plotted. If all samples
+have the same value, only a horizontal line is plotted.
+
+.. note::
+
+    Data sources for reported test results: i) `FD.io test executor vpp
+    performance jobs`_, ii) archived FD.io jobs test result `output files
+    <../../_static/archive/>`_.
