-Packet Throughput
-=================
-
-Throughput graphs are generated based on the results data obtained from
-the |csit-release| test jobs. In order to verify benchmark results
-repeatibility selected, CSIT performance tests are executed multiple
-times (target: 10 times) on each physical testbed type. Box-and-Whisker
-plots are used to display variations in measured throughput values.
-
-Lists of tests selected for multiple execution and graphing are captured
-per testbed type in `test_select_list_{testbed_type}.md
-<https://git.fd.io/csit/tree/docs/job_specs>`_ files.
-
-Graphs are split into sections as follows:
-
-#. **Header 1**: VPP packet path and lookup types
-
- - **L2 Ethernet Switching**: L2 bridge-doman, L2 cross-connect and L2 patch
- - **IPv4 Routing**: IPv4 routing with /32 prefixes
- - **IPv6 Routing**: IPv6 routing with /128 prefixes
- - **SRv6 Routing**: SRv6 with IPv6 routing
- - **IPv4 Tunnels**: IPv4 overlay tunnels
- - **KVM VMs vhost-user**: KVM VMs connected over virtio and vhost-user interfaces
- - **LXC/DRC Container Memif**: Linux containers and Docker containers connected over Memif interfaces
- - **IPsec IPv4 Routing**: IPsec encryption/decryption with IPv4 routing
-
-#. **Header 2**: testbeds and NIC models
-
- - section name format:
-
- - {**testbed_type**}-{**nic_model**}
-
- - **testbed_type**:

-
- - section name format:

- - ixgbe: dpdk poll mode driver for Intel Niantic NICs
-
-For each 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. Outliers are
-plotted as individual points.
-
-Additional information about graph data:
-
-#. **Graph Title**: describes tested packet path, testbed topology,
- processor model, NIC model, packet size, number of cores and
- threads used by data plane workers and indication of VPP DUT
- configuration.
-
-#. **X-axis Labels**: indices of individual test suites as listed in
- Graph Legend.
-
-#. **Y-axis Labels**: measured Packets Per Second [pps] throughput
- values.
-
-#. **Graph Legend**: lists X-axis indices with associated CSIT test
- suites executed to generate graphed test results.
-
-#. **Hover Information**: lists minimum, first quartile, median,
- third quartile, and maximum. If either type of outlier is present the
- whisker on the appropriate side is taken to 1.5×IQR from the quartile
- (the "inner fence") rather than the max or min, and individual outlying
- data points are displayed as unfilled circles (for suspected outliers)
- or filled circles (for outliers). (The "outer fence" is 3×IQR from the
- quartile.)
