Changes in |csit-release|
-------------------------
-#. **VPP performance tests**
+#. **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.
+ - **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.
- - *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.
+ - **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 L2patch, cross linking
+ - **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* - 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
+ - **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 Skylake* - Topologies consisting of 2-node and 3-node using
- SuperMirco servers each equipped with two Intel Xeon Skylake Platinum
- processors.
+ - **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,
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
removal of redundant RF keywords.

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
