#. VPP PERFORMANCE TESTS
- - **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.
-
- - **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.
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
-#. TEST FRAMEWORK
+ - To identify performance changes due to VPP code changes from
+ v20.01.0 to v20.05.0, both have been tested in CSIT environment
+ ver. 4 and compared against each other. All substantial
+ progressions has been marked up with RCA analysis. See
+ :ref:`vpp_compare_current_vs_previous_release` and
+ :ref:`vpp_known_issues`.
- - **Container code optimizations**: Optimized container library allows to
- run containre_memif tests faster.
+#. TEST FRAMEWORK
- - **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.
+ - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
+ still used in CSIT for all VPP scale tests. See known issues below.
- **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.
+ removal of redundant RF keywords and aligning of suite/test
+ setup/teardowns.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs Layout Improvements**: Improved performance graphs layout
+ - **Graphs layout improvements**: Improved performance graphs layout
for better readibility and maintenance: test grouping, axis
labels, descriptions, other informative decoration.

- #. MISCELLANEOUS
-
- - **3n-dnv Tests (3rd Party)**: Published performance tests for 3n-
- dnv (3-Node Atom Denverton) from 3rd party testbeds running FD.io
- |csit-release| automated testing code.
- Only graphs for Packet Throughput and Speedup Multi-core and not
- for Packet Latency were published as there are no results for Packet
- Latency available.
