VPP PERFORMANCE TESTS - - CSIT test environment is versioned, see - :ref:`test_environment_versioning`. - - - To identify performance changes due to VPP code changes from - v20.05.0 to v20.09.0, both have been tested in CSIT environment - ver. 5 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`. - - - **NAT44 tests**: Adapted existing and added new 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. - - Refactored NAT44 deterministic mode (nat44det) tests to use separate - det44 vpp plugin and to use the same scheme of inside and outside - addresses and ports, as used in new NAT44 endpoint-dependent mode tests. - - - Added new NAT44 endpoint-depended mode uni-directional (nat44ed-udir) - tests that measure packet throughput in one direction with usage of TRex - in stateless mode. - - - Added new NAT44 endpoint-dependent mode CPS tests that measure - connections per second with usage of TRex in stateful mode. - NOTE: CPS measurement data will be added in two weeks. +#. TEST FRAMEWORK - - **IPSec async mode tests**: Added VPP performance tests for async crypto - engine. + - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and + SUTs. Included VPP perfmon plugin telemetry with all perfmon + bundles available in VPP release. - - **AMD 2n-zn2 testbed**: New physical testbed type installed in FD.io CSIT, - VPP performance data will be added in upcoming weeks. + - **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. -#. TEST FRAMEWORK + - **CSIT test environment** version has been updated to ver. 7, see + :ref:`test_environment_versioning`. - - **TRex ASTF**: Added capability to run TRex in advanced stateful mode. + - **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.
