VPP PERFORMANCE TESTS - - **Service density 2n-skx tests**: Added higher NF density tests with two - NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now - used as a VNF payload similar to CNF tests. - - - **Soak Tests**: Optimized performamce soak tests framework - code for extended time duration tests and throughput discovery - at given PLR and at give total test time e.g. minutes, hours, - days, weeks. See updated - :ref:`test_methodology` section for more details. + - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel + Atom processors), to later replace 3n-dnv and 2n-dnv (3 and 2 Node + Denverton) testbeds. -#. TEST FRAMEWORK + - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx + testbeds. - - **Qemu code refactor**: Complete code refactor of the key components of - QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added - implementation of kernel-image-kvm based VM replacing the previously used - NestedVM images. Added ability to run VPP as a payload in VNF. + - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr + testbeds) and using built-in hardware crypto QAT device (3n-snr testbed + only). - - **CSIT PAPI Support**: Continued 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. + - **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. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. +#. TEST FRAMEWORK - - **Test suite generator**: Added capability to generate suites for - different NIC models as well as throughput search algorithm types. Uses - base tests suites as source. + - **CSIT test environment** version has been updated to ver. 11, see + :ref:`test_environment_versioning`. - - **TOX verification**: Added verifications for test suite generator. + - **TCP tput profiles** have to be changed, as newer TRex versions + are not deterministic enough when deciding when to send an ACK. -#. PRESENTATION AND ANALYTICS LAYER + - **CSIT PAPI support**: Due to issues with PAPI performance, and + deprecation of VAT, VPP CLI is used in CSIT for many VPP scale + tests. See :ref:`vpp_known_issues`. - - **Graphs Layout Improvements**: Improved performance graphs layout - for better readibility and maintenance: test grouping, axis - labels, descriptions, other informative decoration. + - **General Code Housekeeping**: Ongoing code optimizations and bug + fixes. -.. - #. MISCELLANEOUS +#. PRESENTATION AND ANALYTICS LAYER - - **2n-dnv Tests (3rd Party)**: Published performance tests for 2n- - dnv (2-Node Atom Denverton) from 3rd party testbeds running FD.io - |csit-release| automated testing code. - Only graphs for Packet Throughput and Speedup Multi-core and not - for Packet Latency were published as there are no results for Packet - Latency available. + - **C-Dash** `performance dashboard `_ got updated UI and + updated backend increasing its performance and robustness. .. raw:: latex @@ -61,14 +52,123 @@ Changes in |csit-release| 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.
