CSIT functional and performance tests -have been also developed and merged. However due to the factors beyond CSIT -project control execution of those tests within the LF FD.io test environment -still need to complete. Once the results become available, they will be -published as an addendum to the current version of CSIT |release| report. - -Tests to be Added - SNAT44 --------------------------- - -VPP SNAT44 functionality has been introduced in VPP-17.01 release. CSIT -performance tests are still in development and integration into LFD FD.io test -environment. Once the tests are fully integrated and results become available, -they will be published as an addendum to the current version of CSIT |release| -report. +Release Notes +============= + +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** + + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords. + +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 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 +~~~~~~~~~~~ + +NDR throughput changes between releases are available in a +CSV and pretty ASCII formats: + + -
