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**: Added higher NF density tests with two
+ NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now
+ used as a VNF payload similar to CNF tests.
- - *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.
+ - **Soak Tests**: Optimized 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. 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, ip4,
- l2patch, l2bd, l2xc.
+ - **Qemu code refactor**: Complete code refactor of the key components of
+ QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added
+ implementation of kernel-image-kvm based VM replacing the previously used
+ NestedVM images. Added ability to run VPP as a payload in VNF.
- - *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**: Continued conversion of CSIT VAT L1 keywords to
+ PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components
+ of PAPI Executor and PAPI history.
- - *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.
-
-#. **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**
-
- - *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.
-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.
