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. - - - 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. + - **Intel Xeon Ice Lake**: Performance test data for these platforms + continues to be provided by external Intel benchmarking labs + executing |csit-release| tests. For details about the physical + setup see :ref:`tested_physical_topologies`. - - Added new NAT44 endpoint-dependent mode CPS tests that measure - connections per second with usage of TRex in stateful mode. - See updated methodology sections for more details. + - **AWS EC2 c5n**: Performance test data for AWS c5n instances has + been added to report for ip4, ip6 and ipsec tests. - - Added new NAT44 endpoint-dependent mode PPS tests that measure - packets per second (protocol and data together) with usage of TRex - in stateful mode. See updated methodology sections for more details. - - - **IPSec async mode tests**: Added VPP performance tests for async crypto - engine. - - - **AMD 2n-zn2 testbed**: New physical testbed type installed in FD.io CSIT, - VPP performance data will be added in upcoming weeks. + - **Reduction of tests**: Removed certain test variations executed + iteratively for the report (as well as in daily and weekly + trending) due to physical testbeds overload. #. TEST FRAMEWORK - - **TRex ASTF**: Added capability to run TRex in advanced stateful mode. + - **CSIT test environment** version has been updated to ver. 8, see + :ref:`test_environment_versioning`. - - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is - still used in CSIT for all VPP scale tests. See known issues below. + - **CSIT in AWS environment**: Completed CSIT automation support for + AWS c5n instances environment, including weekly performance + trending tests execution. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords and aligning of suite/test - setup/teardowns. + - **CSIT PAPI support**: Due to issues with PAPI performance, and + deprecation of VAT, CLI is used in CSIT for many VPP scale tests. + See known issues below. - - **Intel E810CQ 100G NIC**: Added configuration for Intel E810CQ 100G NIC. - No tests run for this NIC as it is not present in FD.io CSIT lab yet. + - **General Code Housekeeping**: Ongoing code optimizations and bug + fixes. #.
