6 .. _VPP_Packet_Throughput:
11 Throughput graphs are generated based on the results data obtained from
12 the |csit-release| test jobs. In order to verify benchmark results
13 repeatibility selected, CSIT performance tests are executed multiple
14 times (target: 10 times) on each physical testbed type. Box-and-Whisker
15 plots are used to display variations in measured throughput values.
17 Lists of tests selected for multiple execution and graphing are captured
18 per testbed type in `test_select_list_{testbed_type}.md
19 <https://git.fd.io/csit/tree/docs/job_specs>`_ files.

105 For each test case, Box-and-Whisker plots show the quartiles (Min, 1st
106 quartile / 25th percentile, 2nd quartile / 50th percentile / mean, 3rd
107 quartile / 75th percentile, Max) across collected data set. Outliers are
108 plotted as individual points.
110 Additional information about graph data:
112 #. **Graph Title**: describes tested packet path, testbed topology,
113 processor model, NIC model, packet size, number of cores and
114 threads used by data plane workers and indication of VPP DUT
117 #. **X-axis Labels**: indices of individual test suites as listed in
120 #. **Y-axis Labels**: measured Packets Per Second [pps] throughput
123 #. **Graph Legend**: lists X-axis indices with associated CSIT test
124 suites executed to generate graphed test results.
126 #. **Hover Information**: lists minimum, first quartile, median,
127 third quartile, and maximum. If either type of outlier is present the
128 whisker on the appropriate side is taken to 1.5×IQR from the quartile
129 (the "inner fence") rather than the max or min, and individual outlying
130 data points are displayed as unfilled circles (for suspected outliers)
131 or filled circles (for outliers). (The "outer fence" is 3×IQR from the
