   4 Changes in |csit-release|
   5 -------------------------
   6
   7 #. **DPDK performance tests**
   8
   9    - *MRR tests* - Maximum Receive Rate tests measure the packet forwarding rate
  10      under the maximum load offered by traffic generator over a set trial
  11      duration, regardless of packet loss. MRR tests are used for continuous
  12      performance trending and for comparison between releases.
  13
  14    - *MLR tests* - NDR and PDR tests measure the packet forwarding rate using
  15      MLRsearch library by traffic generator. All tests that previously used
  16      binary search were converted to MLRsearch.
  17
  18    - *2-node tests* - Set of 2-node tests covering testpmd and l3fwd.
  19
  20    - Increased coverage of NIC specific tests (Intel-xxv710-da2, Intel-x710)
  21
  22    - *Generated tests* - Simplified and unified test structure,
  23      semi-autogenerated by generator script. Test generator is currently able
  24      to create test combinations with various frame size and cores combinations.
  25      All existing test cases were converted to new format.

  28 Performance Changes
  29 -------------------
  30
  31 Relative performance changes in measured packet throughput in |csit-release|
  32 are calculated against the results from |csit-release-1|
  33 report. Listed mean and standard deviation values are computed based on
  34 a series of the same tests executed against respective DPDK releases to
  35 verify test results repeatability, with percentage change calculated for
  36 mean values.
