Changes in |csit-release|
-------------------------
-#. **VPP 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.
-
- - *L2patch tests* - Tests measure performance of L2patch, cross linking
- RX and TX of two physical interfaces.
-
- - *2-node tests* - Baseline set of 2-node tests covering base ip4, ip4,
- l2patch, l2bd, l2xc.
-
- - *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 multithreading* - SMT-aware automatic detection and
- resource configuration including thread affinity, number of rx queues and
- DPDK I/O mbufs. Tests are automatically tagged during execution indicating
- configuration.
-
- - *Intel Skylake* - Topologies consisting of 2-node and 3-node using
- SuperMirco servers each equipped with two Intel Xeon Skylake Platinum
- processors.
+#. **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* - Added continuous performance trending and
- analysis. New Performance Trending and Performance Analysis jobs
- executed regular throughput tests, with results being subsequently
- analysed and trend and anomalies summarized and presented in VPP
- Performance Dashboard and trendline graphs.
+ - **Performance trending**: Further improved continuous performance
+ trending with anomaly detection and analysis.
#. **Test Framework Optimizations**
- - *Performance tests efficiency* - Qemu build/install optimizations,
- warmup phase handling, vpp restart handling. Resulted in improved
- stability and reduced total execution time by 30% for single pkt
- size e.g. 64B/78B.
-
- - *General code housekeeping* - ongoing RF keywords optimizations,
- removal of redundant RF keywords.
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
+ removal of redundant RF keywords.
