Changes in |csit-release|
-------------------------
-No code changes apart from bug fixes.
+#. **DPDK performance tests**
+
+ - *MRR tests* - Maximum Receive Rate tests measure the packet forwarding rate
+ under the maximum load offered by traffic generator over a set trial
+ duration, regardless of packet loss. MRR tests are used for continuous
+ performance trending and for comparison between releases.
+
+ - *MLR tests* - NDR and PDR tests measure the packet forwarding rate using
+ MLRsearch library by traffic generator. All tests that previously used
+ binary search were converted to MLRsearch.
+
+ - *2-node tests* - Set of 2-node tests covering testpmd and l3fwd.
+
+ - Increased coverage of NIC specific tests (Intel-xxv710-da2, Intel-x710)
+
+ - *Generated tests* - Simplified and unified test structure,
+ semi-autogenerated by generator script. Test generator is currently able
+ to create test combinations with various frame size and cores combinations.
+ All existing test cases were converted to new format.

Performance Changes
-------------------
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
+a series of the same tests executed against respective DPDK 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.
