Changes in |csit-release|
-------------------------
-#. **VPP 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 VPP 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.
-
- - **L2patch Tests**: Tests measure performance of VPP L2patch, the
- fastest L2 forwarding path implemented in VPP, that cross-links
- RX and TX of two physical interfaces.
-
- - **2-Node Tests**: A new baseline set of 2-node tests covering base
- ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake
- testbeds.
-
- - **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.
-
- - **Simultaneous Multi-Threading**: SMT-aware detection of server
- processor operation mode (HyperThreading enabled/disabled) with
- associated compute resource configuration including thread
- affinity, number of Rx queues and DPDK I/O mbufs. Tests are
- automatically tagged during execution to indicate executed thread
- configuration.
-
- - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node
- physical testbed topologies based on the new SuperMirco servers
- each with two Intel Xeon Skylake Platinum processors. Full
- Ansible playbooks refactor for quick server (re)installation and
- reference pointers of configuration.
-
-#. **Presentation and Analytics Layer**
-
- - **Performance trending**: Further improved continuous performance
- trending with anomaly detection and analysis.
-
-#. **Test Framework Optimizations**
+#. VPP PERFORMANCE TESTS
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.
-
-Performance Changes
--------------------
-
-Relative performance changes in measured NDR, PDR and MRR packet
-throughput in |csit-release| are calculated against the test results
-from |csit-release-1| report, for tests running on 3-Node Intel Xeon
-Haswell testbeds (3n-hsw) in 1-core, 2-core and 4-core (MRR only)
-configurations.
+ - **Service density 2n-skx tests**: Added higher NF density tests with two
+ NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now
+ used as a VNF payload similar to CNF tests.
-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
-~~~~~~~~~~~
+ - **Soak Tests**: Optimized performamce soak tests framework
+ code for extended time duration tests and throughput discovery
+ at given PLR and at give total test time e.g. minutes, hours,
+ days, weeks. See updated
+ :ref:`test_methodology` section for more details.
-NDR throughput changes between releases are available in CSV and pretty
-ASCII formats:

+ QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added
+ implementation of kernel-image-kvm based VM replacing the previously used
+ NestedVM images. Added ability to run VPP as a payload in VNF.

-Throughput Trending
--------------------
-
-In addition to reporting throughput changes between VPP releases, CSIT
-provides continuous performance trending for VPP master branch:
-
-#. `VPP Performance Dashboard <https://docs.fd.io/csit/master/trending/introduction/index.html>`_
- - per VPP test case throughput trend, trend compliance and summary of
- detected anomalies.
-
-#. `Trending Methodology <https://docs.fd.io/csit/master/trending/methodology/index.html>`_
- - throughput test metrics, trend calculations and anomaly
- classification (progression, regression, outlier).
-
-#. `Trendline Graphs <https://docs.fd.io/csit/master/trending/trending/index.html>`_
- - per VPP build MRR throughput measurements against the trendline
- with anomaly highlights, with associated CSIT test jobs.
