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.

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