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.
+ - **Service density 2n-skx tests**: Network Function Virtualization (NFV)
+ service density tests focus on measuring total per server throughput at
+ varied NFV service *packing* densities with vswitch providing host
+ dataplane. The goal is to compare and contrast performance of a shared
+ vswitch for different network topologies and virtualization technologies,
+ and their impact on vswitch performance and efficiency in a range of NFV
+ service configurations.
- - *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.
+ - **Experimental Soak Tests**: Added 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, months, years. See updated
+ :ref:`test_methodology` section for more details.
- - *L2patch tests* - Tests measure performance of L2patch, cross linking
- RX and TX of two physical interfaces.
+#. TEST FRAMEWORK
- - *2-node tests* - Baseline set of 2-node tests covering base ip4, ip6,
- l2patch, l2bd, l2xc.
+ - **Container code optimizations**: Optimized container library allows to
+ run containre_memif tests faster.
- - *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.
+ - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to
+ PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away
+ from VAT.
- - *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. 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.
-
-#. **Test Framework Optimizations**
-
- - *General code housekeeping* - ongoing RF keywords 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.
