+VPP Performance Dashboard
+=========================
+
+Description
+-----------
+
+Performance dashboard tables provide the latest VPP throughput trend,
+trend compliance and detected anomalies, all on a per VPP test case
+basis.  Linked trendline graphs enable further drill-down into the
+trendline compliance, sequence and nature of anomalies, as well as
+pointers to performance test builds/logs and VPP builds. Performance
+trending is currently based on the Maximum Receive Rate (MRR) tests. MRR
+tests measure the packet forwarding rate under the maximum load offered
+by traffic generator over a set trial duration, regardless of packet
+loss. See :ref:`trending_methodology` section for more detail including
+trend and anomaly calculations.
+
+Data samples are generated by the CSIT VPP performance trending jobs
+executed twice a day (target start: every 12 hrs, 02:00, 14:00 UTC). All
+trend and anomaly evaluation is based on a rolling window of <N=14> data
+samples, covering last 7 days.
+
+Legend to table:
+
+    - **Test Case** : name of FD.io CSIT test case, naming convention
+      `here <https://wiki.fd.io/view/CSIT/csit-test-naming>`_.
+    - **Trend [Mpps]** : last value of performance trend.
+    - **Short-Term Change [%]** : Relative change of last trend value
+      vs. last week trend value.
+    - **Long-Term Change [%]** : Relative change of last trend value vs.
+      maximum of trend values over the last quarter except last week.
+    - **Regressions [#]** : Number of regressions detected.
+    - **Progressions [#]** : Number of progressions detected.
+    - **Outliers [#]** : Number of outliers detected.
+
+Tested VPP worker-thread-core combinations (1t1c, 2t2c, 4t4c) are listed
+in separate tables in section 1.x. Followed by trending methodology in
+section 2. and trendline graphs in sections 3.x. Performance test  data
+used for trendline graphs is provided in sections 4.x.
