VPP PERFORMANCE TESTS - - **Experimental Soak Tests**: Added 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, months, years. See updated - :ref:`test_methodology` section for more details. + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. -#. TEST FRAMEWORK + - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels. + See :ref:`geneve_methodology` for more details. - - **Container code optimizations**: Optimized container library allows to - run containre_memif tests faster. - - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to - PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away - from VAT. + - **GSO tests**: Added VPP performance tests for GSOtap and GSOvirtio. + All tested topologies are compared with GSO enabled and disabled. + In |csit-release| there is only 1t1c tests running. + See :ref:`gso_methodology` for more details. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. -#. PRESENTATION AND ANALYTICS LAYER + - **NAT44 tests**: Added new test type, pure throughput tests. + They are similar to PPS tests, but they employ ramp-up trials + to ensure all sessions are created (and not timing out) + for performance trials. + + - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled + in ipsec suites. - - **Graphs Layout Improvements**: Improved performance graphs layout - for better readibility and maintenance: test grouping, axis - labels, descriptions, other informative decoration. + - **Randomized profiles**: Improved repeatability and cycle length. + For details, see :ref:`packet_flow_ordering`. -#. MISCELLANEOUS + - **Arm 2n-tx2 testbed**: New physical testbed type installed in + FD.io CSIT, with VPP and DPDK performance data added to CSIT + trending and this report. - - **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. + - **Framework speedup**: Shortened overall test job duration + by using a different test selection mechanism (using --test + instead of --include) and by avoiding unnecessary PAPI reconnects. + +#. TEST FRAMEWORK -.. note:: + - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode. + + - **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, + speed ups and bug fixes. + +#. PRESENTATION AND ANALYTICS LAYER - The Report rls1901.1 was generated with only 1 run of performance tests, - ie. the data are not statistically significant. - The NFV tests were not run so this section has been removed from the - report. + - **Graphs improvements**: Updated Packet Latency graphs, + see :ref:`latency_methodology`. .. raw:: latex @@ -57,24 +64,40 @@ 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.
