VPP PERFORMANCE TESTS - - **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. + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. -#. TEST FRAMEWORK - - - **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. + - To identify performance changes due to VPP code changes from + v20.01.0 to v20.05.0, both have been tested in CSIT environment + ver. 4 and compared against each other. All substantial + progressions has been marked up with RCA analysis. See + :ref:`vpp_compare_current_vs_previous_release` and + :ref:`vpp_known_issues`. - - **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 FRAMEWORK - - **Test Suite Generator**: Added capability to generate suites for - different drivers per NIC model including DPDK, AVF, RDMA. - Extended coverage for all tests. + - **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 RF keywords optimizations, removal of redundant RF keywords and aligning of suite/test setup/teardowns. -#. 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 - `_]. - - - **New Intel Xeon Cascadelake Testbeds**: Added performance tests - for 2-Node-Cascadelake (2n-clx) testbeds with x710, xxv710 and - mcx556a-edat NIC cards. - #. PRESENTATION AND ANALYTICS LAYER - **Graphs layout improvements**: Improved performance graphs layout for better readibility and maintenance: test grouping, axis labels, descriptions, other informative decoration. - - **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.
