Release Notes
=============
#. 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.
+ - **Enhanced and added VPP hoststack tests** to daily and weekly
+ trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3,
+ LD_PRELOAD NGINX.
+
+ - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending
+ and report, in addition to RDMA_CORE ones that were already
+ there.
+
+ - **Jumbo frames tests** got fixed and re-added number of to report
+ coverage tests.
+
+ - **Intel Xeon SKX performance testbeds** got decommissioned and
+ removed from FD.io performance lab.
+
+#. TEST FRAMEWORK
+
+ - **CSIT test environment** version has not changed from ver. 11 used
+ in previous release, see :ref:`test_environment_versioning`.
+
+ - **CSIT PAPI optimizations for scale** got applied improving PAPI
+ programming speed especially for large scale tests. VAT has been
+ now completely deprecated from CSIT.
+
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **Performance trending**: Further improvements of continuous
- performance trending, anomaly detection and analysis.
+ - `Performance dashboard <http://csit.fd.io/>`_ got updated with
+ addition of VPP telemetry trending across all VPP tests. A number
+ of code and AWS resource usage optimizations got applied to the
+ data processing pipeline and UI frontend and backend.
-#. TEST FRAMEWORK OPTIMIZATIONS
+ - Examples of release iterative data visualisation:
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.
+ - `Packet throughput 2n-icx-e810cq-ip4-base-scale-pdr <https://csit.fd.io/report/#eNrdVcluwjAQ_Zr0ggbZDml64QDkP5BxhhJlwYxNVPr1OAhpYiGO7cEHb3pv1qeRnT8T7h1266zYZuU2U2VThy3LN4twUOdULhSM1oLKl-FG2KF2CGqAxvyAFOIblZX4JYW5gB6P0NgVfK4OIA2gP02vsA6Tja1pcq12T9cvcRitr57RED1CRiQGo7SYZk-3GeddsszXhJoNQsYMeXSzZOKamHUk3aNrfpGpoQuMm9BohqSJ_fubnaHPRpXVg_F3qjijO1RCtEBDnZo8UXFJ6NQmKlGbgjp9ujPU_8cEFdXHcKb-8Q8V1R2PI8PX>`_
