Release Notes
=============
Changes in |csit-release|
-------------------------
#. **DPDK performance tests**
- **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
configurable trial duration and number of consecutive executions.
Coverage of MRR tests has been extended across more test
scenarios. MRR tests are used for continuous performance trending
and for comparison between DPDK releases.
- **MLRsearch Throughput**: MLRsearch algorithm has been introduced
for all NDR and PDR throughput tests. All tests that previously
used binary search got converted to MLRsearch. Coverage of NDR/PDR
tests has been extended across more test scenarios.
- **2-Node Tests**: A new set of 2-node tests covering DPDK Testpmd
and L3fwd, running on new Xeon Skylake testbeds.
- **More NICs**: Increased coverage of NIC models tested: Intel-
xxv710-da2, Intel-x710-da4.
- **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.
#. **Presentation and Analytics Layer**
- **Performance trending**: Added continuous performance trending with
anomaly detection and analysis for DPDK.
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:
