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. + - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP performance + test data is not included in this report version. This is due to + the lower performance and behaviour inconsistency of these + systems following the upgrade of processor microcode packages + (skx ucode 0x2000064, clx ucode 0x500002c), done as part of + updating Ubuntu 18.04 LTS kernel version. Tested VPP and DPDK + applications (L3fwd) are affected. Skx and Clx test data will be + added in subsequent maintenance report version(s) once the issue + is resolved. See :ref:`vpp_known_issues`. + + - **Service density 2n-skx tests**: Added new NF density tests with + IPsec encryption between DUTs. + + - **AVF tests**: Full test coveraged based on code changes in CSIT + core layer (driver/interface awareness) and generated by suite + generator (Intel Fortville NICs only). + + - **Hoststack tests**: Major refactor of VPP Hoststack TCP/IP + performance tests using WRK generator talking to the VPP HTTP + static server plugin measuring connections per second and + requests per second. Added new iperf3 with LDPreload tests, + iperf3/LDPreload tests with packet loss induced via the VPP NSIM + (Network Simulator) plugin, and QUIC/UDP/IP transport tests. + All of the new tests measure goodput through the VPP Hoststack + from client to server. + + - **Latency HDRHistogram**: Added High Dynamic Range Histogram + latency measurements based on the new capability in TRex traffic + generator. HDRH latency data presented in latency packet + percentile graphs and in detailed results tables. + + - **Mellanox MCX556A-EDAT tests**: Added tests with Mellanox + ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma + driver. + + - **IPsec reconfiguration tests**: Added tests measuring the impact + of IPsec tunnels creations and removals. + + - **Load Balancer tests**: Added VPP performance tests for Maglev, + L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode. #. TEST FRAMEWORK - - **Container code optimizations**: Optimized container library allows to - run containre_memif tests faster. + - **CSIT Python3 support**: Full migration of CSIT from Python2.7 to + Python3.6. This change includes library migration, PIP dependency + upgrade, CSIT container images, infrastructure packages + ugrade/installation. - - **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. + - **CSIT PAPI support**: Finished conversion of CSIT VAT L1 keywords + to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI). + Redesign of key components of PAPI Socket Executor and PAPI + history. Due to issues with PAPI performance, VAT is still used + in CSIT for all VPP scale tests. See known issues below. + + - **Test Suite Generator**: Added capability to generate suites for + different drivers per NIC model including DPDK, AVF, RDMA. + Extended coverage for all tests. - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. + removal of redundant RF keywords and aligning of suite/test + setup/teardowns. + #. PRESENTATION AND ANALYTICS LAYER - - **Graphs Layout Improvements**: Improved performance graphs layout + - **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. + - **Latency graphs**: Min/Avg/Max group bar latency graphs are + replaced with packet latency percentile distributon at different + background packet loads based on TRex latency hdrhistogram + measurements. + +.. + // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published + - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP performance + test data is included in this report version, but it shows lower + performance and behaviour inconsistency of these systems + following the upgrade of processor microcode packages (skx ucode + 0x2000064, clx ucode 0x500002c) as part of updating Ubuntu 18.04 + LTS kernel version.
