VPP PERFORMANCE TESTS - - **Service density 2n-skx tests**: Added higher NF density tests with - 802.1q (vlan) and VXLAN encapsulation from Traffic Generator. - - - **GBP tests**: Added GBP (Group Based Policy) routing test cases - with 802.1q (vlan) external traffic. - - - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and - scale test cases (Fortville NICs only). - - - **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 IPsec tunnels. - Removed DPDK backend dependency. Major IPsec test code - refactoring. - - - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP - performance tests using WRK generator talking to the VPP HTTP - static server plugin measuring connections per second and - requests per second. - - - **Changed methodology of dot1q tests in 2-Node testbeds**: 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 all dot1q tests in all 2-Node - testbeds. - - - **KVM VM vhost-user tests**: completed move to Kernel-VM for all - tests. In addition to running DPDK Testpmd as VM workload, new - tests created with VPP as VM workload. VPP in VM is the same - version as the DUT VPP (acting as vSwitch) and its configuration - depends on the test type. For all L2 Ethernet Switching tests - it's vpp-l2xc (L2 cross-connect), for all IPv4 Routing tests it's - vpp-ip4 (VPP IPv4 routing). + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. + + - 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 (VPP PAPI). - Redesign of key components of PAPI Socket Executor and PAPI - history. Due to issues with PAPI performance, VAT is still used - in CSIT for all VPP scale tests. See known issues below. + - **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. @@ -73,46 +42,78 @@ Known Issues List of known issues in |csit-release| for VPP performance tests: -+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+ -| # | JiraID | Issue Description | -+====+=========================================+==========================================================================================================+ -| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
