-Performance Changes
--------------------
+.. raw:: latex
-Relative performance changes in measured NDR, PDR and MRR packet
-throughput in |csit-release| are calculated against the test results
-from |csit-release-1| report, for tests running on 3-Node Intel Xeon
-Haswell testbeds (3n-hsw) in 1-core, 2-core and 4-core (MRR only)
-configurations.
+ \clearpage
-Listed mean and standard deviation values are computed based on a series
-of the same tests executed against respective VPP releases to verify
-test results repeatability, with percentage change calculated for mean
-values. Note that the standard deviation is quite high for a small
-number of packet throughput tests, what indicates poor test results
-repeatability and makes the relative change of mean throughput value not
-fully representative for these tests. The root causes behind poor
-results repeatability vary between the test cases.

-Throughput Trending
--------------------
-
-In addition to reporting throughput changes between VPP releases, CSIT
-provides continuous performance trending for VPP master branch:
-
-#. `VPP Performance Dashboard <https://docs.fd.io/csit/master/trending/introduction/index.html>`_
- - per VPP test case throughput trend, trend compliance and summary of
- detected anomalies.
-
-#. `Trending Methodology <https://docs.fd.io/csit/master/trending/methodology/index.html>`_
- - throughput test metrics, trend calculations and anomaly
- classification (progression, regression, outlier).
-
-#. `Trendline Graphs <https://docs.fd.io/csit/master/trending/trending/index.html>`_
- - per VPP build MRR throughput measurements against the trendline
- with anomaly highlights, with associated CSIT test jobs.
