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 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. + - **AF_XDP**: Added af_xdp driver support for all test cases. Test + results will be added in sub-sequent CSIT-2106 report. + + - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests. + + - **Intel Xeon Ice Lake**: Added initial test data for these + 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 details about the + physical setup see :ref:`tested_physical_topologies`. Tested + VPP and CSIT versions are pre-release, VPP + 21.06-rc0~779-gd640ae52f. + + - **MLRsearch improvements**: Added support for multiple packet + throughput rates in a single search, each rate is associated + with a distinct Packet Loss Ratio (PLR) criterion. Previously + only Non Drop Rate (NDR) (PLR=0) and single Partial Drop Rate + (PDR) (PLR<0.5%) were supported. Implemented number of + optimizations improving rate discovery efficiency. + + - **Reduction of tests**: Removed obsolete VPP use cases and + superfluous test combinations from continuous and report test + executions, including: + + - All vts tests, obsolete use cases. + - dot1q tests apart from dot1q-l2bd, superfluous combinations. + - -100flows, -100kflows in all acl tests. + - nat44 tests + + - -pps tests, replaced by -tput tests. + - h1-p1-s1 single session tests, unessential combination. + - h4096-p63-s258048 tests, unessential scale combination. + + - ipsec tests + + - ethip4ipsectptlispgpe. + - policy-aes128gcm. + - policy-aes128cbc-hmac256sha. + - policy-aes128cbc-hmac512sha. + - int-aes128cbc-hmac256sha. + - scale of + + - 400tnlsw. + - 5000tnlsw. + - 20000tnlsw. + - 60000tnlsw. - - **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. +#. TEST FRAMEWORK - - **Load Balancer tests**: Added VPP performance tests for Maglev, - L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode. + - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and + SUTs. Included VPP perfmon plugin telemetry with all perfmon + bundles available in VPP release. -#. TEST FRAMEWORK + - **Upgrade to Ubuntu 20.04 LTS**: Re-installed base operating system + to Ubuntu 20.04.2 LTS. Upgrade included also baseline Docker + containers used for spawning topology. - - **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. + - **TRex upgrade v2.86 to v2.88**: Included move to DPDK 21.02 and + changed the way egress low latency queues are used in FVL NICs. + This broke latency measurements for majority of FVL NICs in + CSIT. Latency values look better after upgrading FVL FW on TRex + servers, but still somewhat higher than before the TRex upgrade. + Tracked by `CSIT-1790 `_. - - **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. + - **CSIT test environment** version has been updated to ver. 7, see + :ref:`test_environment_versioning`. - - **Test Suite Generator**: Added capability to generate suites for - different drivers per NIC model including DPDK, AVF, RDMA. - Extended coverage for all tests. + - **CSIT in AWS environment**: Added CSIT support for AWS c5n + instances environment. Test results will be added in sub-sequent + CSIT-2106 report. - - **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 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 +105,33 @@ 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.
