VPP PERFORMANCE TESTS - - **Intel Xeon 2n-skx, 3n-skx testbeds**: VPP performance test data - is now included in this report version. Due to substantial impact - of test environment changes (applied during the CSIT-2001 - development cycle) on the performance of VPP software, a new - approach to performance comparison and progression/regression - root cause analysis (RCA) has been applied. - - - CSIT test environment is now versioned, with ver. 1 associated - with CSIT rls1908 git branch as of 2019-08-21, and ver. 2 - associated with CSIT rls2001 git branch as of 2020-03-27. - - - To identify performance changes due to CSIT test environment - changes from ver. 1 to ver. 2, VPP v19.08.1 has been re-tested in - ver. 2 and compared against the past results obtained with - testing in ver. 1.

See - :ref:`vpp_compare_current_vs_previous_release` and - :ref:`vpp_known_issues`. - - - **Intel Xeon 2n-clx testbeds**: VPP performance test data is now - included in this report. 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 + - **Enhanced and added VPP hoststack tests** to daily and weekly + trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3, + LD_PRELOAD NGINX. - - **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. + - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending + and report, in addition to RDMA_CORE ones that were already + there. - - **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. + - **Jumbo frames tests** got fixed and re-added number of to report + coverage tests. - - **Test Suite Generator**: Added capability to generate suites for - different drivers per NIC model including DPDK, AVF, RDMA. - Extended coverage for all tests. + - **Intel Xeon SKX performance testbeds** got decommissioned and + removed from FD.io performance lab. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords and aligning of suite/test - setup/teardowns. +#. TEST FRAMEWORK -#. TEST ENVIRONMENT + - **CSIT test environment** version has not changed from ver. 11 used + in previous release, see :ref:`test_environment_versioning`. - - **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 - `_]. + - **CSIT PAPI optimizations for scale** got applied improving PAPI + programming speed especially for large scale tests.
