#. VPP PERFORMANCE TESTS
- - **Service density 2n-skx tests**: Added higher NF density tests with
- 802.1q (vlan) and 802.1ad (vxlan) encapsulation from Traffic Generator.
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
- - **GBP tests**: Added GBP routing test cases with 802.1q (vlan) external
- traffic.
-
- - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and scale
- test cases.
-
- - **2n-skx tests**: Increased coverage of selected (COP, iACL, Policer)
- test cases.
-
- - **IPsec scale tests**: Added IPsec interface mode scale tests with
- 1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 tunnels. Removed DPDK
- backend dependency.
-
- - **Hoststack TCP tests**: Added Hoststack TCP performance tests
- using WRK to the HTTP static server plugin measuring connections
- per second and requests per second.
-
- - **Changed methodology of dot1q 2n tests**: dot1q encapsulation is now used
- on both links of SUT. Previously dot1q was used only on a single link with
- the other link carrying untagged Ethernet frames. This change results in
- slightly lower throughput in CSIT-1908 for these tests.
+ - 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`.
#. TEST FRAMEWORK
- - **CSIT PAPI Support**: Finished 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. Currently the only exception is
- usage of VAT command for scale configuration.
+ - **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 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.

+| 4 | `CSIT-1591 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
