Release Notes
=============
Changes in |csit-release|
-------------------------
#. **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 DPDK releases to
verify test results repeatability, with percentage change calculated for
mean values.
NDR Changes
~~~~~~~~~~~
NDR throughput changes between releases are available in a CSV and pretty ASCII
formats:
- `csv format for 1t1c <../_static/dpdk/performance-changes-1t1c-ndr.csv>`_,
- `csv format for 2t2c <../_static/dpdk/performance-changes-2t2c-ndr.csv>`_,
- `pretty ASCII format for 1t1c <../_static/dpdk/performance-changes-1t1c-ndr.txt>`_,
- `pretty ASCII format for 2t2c <../_static/dpdk/performance-changes-2t2c-ndr.txt>`_.
.. note::
Test results have been generated by
`FD.io test executor dpdk performance job 3n-hsw`_
with Robot Framework result
files csit-dpdk-perf-|srelease|-\*.zip
`archived here <../_static/archive/>`_.
PDR Changes
~~~~~~~~~~~
PDR throughput changes between releases are available in a CSV and pretty ASCII
formats:
- `csv format for 1t1c <../_static/dpdk/performance-changes-1t1c-pdr.csv>`_,
- `csv format for 2t2c <../_static/dpdk/performance-changes-2t2c-pdr.csv>`_,
- `pretty ASCII format for 1t1c <../_static/dpdk/performance-changes-1t1c-pdr.txt>`_,
- `pretty ASCII format for 2t2c <../_static/dpdk/performance-changes-2t2c-pdr.txt>`_.

Comparison Across Testbeds
--------------------------
Relative performance changes in measured packet throughput on 3-Node Skx testbed
are calculated against the results measured on 3-Node Hsw testbed.
NDR Changes
~~~~~~~~~~~
NDR throughput changes between testbeds are available in a CSV and pretty ASCII
formats:
- `csv format for ndr <../_static/dpdk/performance-compare-testbeds-3n-hsw-3n-skx-ndr.csv>`_,
- `pretty ASCII format for ndr <../_static/dpdk/performance-compare-testbeds-3n-hsw-3n-skx-ndr.txt>`_.
.. note::
Test results have been generated by
`FD.io test executor dpdk performance job 3n-hsw`_ and
`FD.io test executor dpdk performance job 3n-skx`_
with Robot Framework result
