 Packet Throughput
 =================
 
-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 throughput 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.
-
-*Title of each graph* describes the packet path, testbed topology, processor
-architecture, packet size, number of cores and threads used by workers and
-DUT configuration, *X-axis labels* are indices of individual test suites
-executed by FD.io test executor vpp performance jobs that created result output
-files used as data sources for the graph, *Y-axis labels* are measured Packets
-Per Second [pps] values, and the *Graph legend* lists the plotted test suites
-and their indices.
