VPP PERFORMANCE TESTS - - - **AF_XDP**: Added af_xdp driver support for all test cases. Test - results will be added in sub-sequent CSIT-2106 report. - - - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests. - - - **Intel Xeon Ice Lake**: Added initial test data for these - platforms. Current CSIT-2106 report data for Intel Xeon Ice Lake - comes from an external source (Intel labs running CSIT code on - "8360Y D Stepping" and "6338N" processors). For details about the - physical setup see :ref:`tested_physical_topologies`. Tested - VPP and CSIT versions are pre-release, VPP - 21.06-rc0~779-gd640ae52f. - - - **MLRsearch improvements**: Added support for multiple packet - throughput rates in a single search, each rate is associated - with a distinct Packet Loss Ratio (PLR) criterion. Previously - only Non Drop Rate (NDR) (PLR=0) and single Partial Drop Rate - (PDR) (PLR<0.5%) were supported. Implemented number of - optimizations improving rate discovery efficiency. - - - **Reduction of tests**: Removed obsolete VPP use cases and - superfluous test combinations from continuous and report test - executions, including: - - - All vts tests, obsolete use cases. - - dot1q tests apart from dot1q-l2bd, superfluous combinations. - - -100flows, -100kflows in all acl tests. - - nat44 tests - - - -pps tests, replaced by -tput tests. - - h1-p1-s1 single session tests, unessential combination. - - h4096-p63-s258048 tests, unessential scale combination. - - - ipsec tests - - - ethip4ipsectptlispgpe. - - policy-aes128gcm. - - policy-aes128cbc-hmac256sha. - - policy-aes128cbc-hmac512sha. - - int-aes128cbc-hmac256sha. - - scale of - - - 400tnlsw. - - 5000tnlsw. - - 20000tnlsw. - - 60000tnlsw. - -#. TEST FRAMEWORK - - - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and - SUTs. Included VPP perfmon plugin telemetry with all perfmon - bundles available in VPP release. - - - **Upgrade to Ubuntu 20.04 LTS**: Re-installed base operating system - to Ubuntu 20.04.2 LTS. Upgrade included also baseline Docker - containers used for spawning topology. - - - **CSIT test environment** version has been updated to ver. 7, see - :ref:`test_environment_versioning`. - - - **CSIT in AWS environment**: Added CSIT support for AWS c5n - instances environment. Test results will be added in sub-sequent - CSIT-2106 report. - - - **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 code optimizations and bug - fixes. - -#. PRESENTATION AND ANALYTICS LAYER - - - **Graphs improvements**: Updated Packet Latency graphs, - see :ref:`latency_methodology`. - -.. raw:: latex - - \clearpage - -.. _vpp_known_issues: - -Known Issues ------------- - -List of known issues in |csit-release| for VPP performance tests: - -+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ -| # | JiraID | Issue Description | -+====+=========================================+===========================================================================================================+ -| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. | -| | `_ | | -+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ -| 2 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. | -| | `_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. | -+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ -| 3 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much | -| | `_ | longer to program VPP).
