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:`performance_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. + - **Intel Xeon 2n-skx, 3n-skx 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), done as part of updating Ubuntu 18.04 LTS kernel + version. Tested VPP and DPDK applications (L3fwd) are affected. + Skx test data will be added in subsequent maintenance report + version(s) once the issue is resolved. See + :ref:`vpp_known_issues`. + + - **Intel Xeon 2n-clx testbeds**: VPP performance test data is now + included in this report, after resolving the issue of lower + performance and behaviour inconsistency of these systems due to + the Linux kernel driven upgrade of processor microcode packages + to 0x500002c. The resolution is to use latest SuperMicro BIOS 3.2 + (for X11DPG-QT motherboards used) that upgrades processor + microcode to 0x500002c, AND NOT kernel provided ucode package as + it does put system into sub-optimal state. Subset of 2n-clx VPP + tests are failing due to clx system behaviour change: i) all ip4 + tests with xxv710 and avf driver and ii) some cx556a rdma tests. + 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 CX556A-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 - - **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:`performance_test_methodology` section for more details. - - - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily - trending. + - **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. - - **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. + - **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. - - **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"). + - **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. - -#. PRESENTATION AND ANALYTICS LAYER + removal of redundant RF keywords and aligning of suite/test + setup/teardowns. - - **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(!) +#. TEST ENVIRONMENT + - **TRex Fortville NIC Performance**: Received FVL fix from Intel + resolving TRex low throughput issue. TRex per FVL NIC throughput + increased from ~27 Mpps to the nominal ~37 Mpps. For detail see + `CSIT-1503 `_ and `TRex-519 + `_]. - - **Performance Trending**: Further improvements of continuous - performance trending, anomaly detection and analysis. + - **New Intel Xeon Cascadelake Testbeds**: Added performance tests + for 2-Node-Cascadelake (2n-clx) testbeds with x710, xxv710 and + cx556a-edat NIC cards. -#.
