+Release Notes

-Changes in CSIT |release|
+Changes in |csit-release|
-------------------------
-#. Improved Testpmd tests
+No code changes apart from bug fixes.
- - Performance of NICs - 2p40GE Intel xl710, 2p10GE Intel x710
+Performance Changes
+-------------------
-#. Added L3FWD tests on 2p10GE Intel x520-DA2
+Relative performance changes in measured packet throughput in |csit-release|
+are calculated against the results from |csit-release-1|
+report. 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.
+
+NDR Changes

+NDR throughput changes between releases are available in a
