Maximum load for - specified Ethernet frame size is set to the bi-directional link - rate. MRR tests are used for continuous performance trending and - for comparison between releases. - - - **Service Chaining with SRv6** : SRv6 (Segment Routing IPv6) proxy tests - verifying performance of Endpoint to SR-unaware appliance via - masquerading (End.AM), dynamic proxy (End.AD) or static proxy (End.AS) - functions. - -#. **Presentation and Analytics Layer (PAL)** - - - Added continuous performance measuring, trending and anomaly - detection. Includes new PAL code and Jenkins jobs for Performance - Trending (PT) and Performance Analysis (PA) producing performance - trending dashboard and trendline graphs with summary and drill- - down views across all specified tests that can be reviewed and - inspected regularly by FD.io developers and users community. - -#. **Test Framework Optimizations** - - - **Performance tests efficiency** : Qemu build/install - optimizations, warmup phase handling, vpp restart handling. - Resulted in improved stability and reduced total execution time by - 30% for single pkt size e.g. 64B/78B. - - - **General code housekeeping** : ongoing RF keywords - optimizations, removal of redundant RF keywords. - -Performance Changes -------------------- - -Relative performance changes in measured packet throughput in CSIT -|release| are calculated against the results from CSIT |release-1| -report. Listed mean and standard deviation values are computed based on -a series of the same tests executed against respective VPP releases to -verify test results repeatibility, with percentage change calculated for -mean values. Note that the standard deviation is quite high for a small -number of packet throughput tests, what indicates poor test results -repeatability and makes the relative change of mean throughput value not -fully representative for these tests.

VPP PERFORMANCE TESTS + + - **BMRR Throughput**: MRR (Maximum Receive Rate) test code has been + updated with a configurable burst MRR parameters: trial duration + and number of trials in a single burst. Enables a new Burst MRR + (BMRR for short) methodology for more precise performance + trending. See updated :ref:`test_methodology` section + for more details. + + - **2n-skx tests**: Added performamce tests for 2n-skx (2-Node Xeon + Skylake) testbeds: focus on baseline and scale tests, including + VM vhost and Container memif tests. + + - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon + Skylake) testbeds: VM vhost and Container memif tests. + + - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with + dot1q and VPP L2BD. + + - **AVF Driver Tests**: Added performamce tests for i40e AVF driver + on VPP, no DPDK required. + + - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards. + + - **VM Vhost Virtio Params Combinations**: Added performance tests + for VM vhost with different virtio parameters combinations: + indirect buffers, mergeable buffers. + + - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests + to daily trending. + +#. TEST FRAMEWORK + + - **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. + + - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily + trending. + + - **Per VPP Patch Performance Checks**: Per VPP gerrit patch vs. + parent performance tests, anomaly detection and no verify voting + (-1/0/+1) yet. Manual trigger only. Not "marketed" to FD.io + community yet to avoid excessive LFN FD.io physical performance + testbed blocking. + + - **Patch-on-Patch Infra**: Added capability to run performance tests + using CSIT gerrit patch code testing VPP gerrit patch code, i.e. + before any VPP and/or CSIT code is merged into git branch. + + - **CSIT PAPI Support**: Initial implementation of PAPI L1 KWs in + CSIT using VPP Python bindings. Required for migraing away from + VAT. Very few L1 KWs implemented ("show version", "show + interfaces"). + + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords. + +#. PRESENTATION AND ANALYTICS LAYER + + - **Graphs Layout Improvements**: Improved performance graphs layout + for better readibility and maintenance: test grouping, axis + labels, descriptions, other informative decoration. Master report + generated. 744 graphs(!) + + - **Performance Trending**: Further improvements of continuous + performance trending, anomaly detection and analysis. + +#. MISCELLANEOUS + + - **3n-dnv Tests (3rd Party)**: Published performance tests for 3n- + dnv (3-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.
