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. + +#. TEST FRAMEWORK + + - **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. + + - **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. + + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords. + + - **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. + + - **TOX verification**: Added verifications for test suite generator. + +#. PRESENTATION AND ANALYTICS LAYER + + - **Graphs Layout Improvements**: Improved performance graphs layout + for better readibility and maintenance: test grouping, axis + labels, descriptions, other informative decoration. + +.. + #. MISCELLANEOUS + + - **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. + +.. raw:: latex + + \clearpage + +.. _vpp_known_issues: + +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.
