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. + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. - - **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). + - **Upgrade to Ubuntu 20.04 LTS**: Reinstall base operating system to + Ubuntu 20.04.2 LTS. Upgrade includes also baseline Docker + containers used for spawning topology. - - **Hoststack TCP/IP 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 iperf3 tests with LDPreload. + - Initial test data for Intel Xeon Ice Lake platforms. Current + CSIT-2106 report data for Intel Xeon Ice Lake comes from an + external source (Intel labs running CSIT code on 8360Y D Stepping + and 6338N processors). For detail about the physical setup + see :ref:`tested_physical_topologies`. Tested VPP and CSIT + versions are pre-release, VPP 21.06-rc0~779-gd640ae52f. - - **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. + - **AF_XDP**: Added af_xdp driver testing for all testcases. - - **Mellanox MCX556A-EDAT tests**: Added tests with Mellanox - ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma - driver. + - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests. - - **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. + - **Telemetry retouch**: Redesign telemetry retrieval from DUT. + Include VPP perfmon plugin telemetry. #. 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. - - - **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 and aligning of suite/test - setup/teardowns. + - **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 code optimizations, + speed ups and bug fixes. #. 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. + - **Graphs improvements**: Updated Packet Latency graphs, + see :ref:`latency_methodology`. .. raw:: latex @@ -89,32 +56,27 @@ 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.
