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. Separate RCA1 analysis has been applied to + this part. See :ref:`vpp_compare_current_vs_previous_release` and + :ref:`vpp_known_issues`. + + - To identify performance changes due to VPP code changes from + v19.08.1 to v20.01.0, both have been tested in CSIT environment + ver. 2 and compared against each other. Separate RCA2 analysis + has been applied to this part. 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 + + - **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. + +#. 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 + cx556a-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. + +.. raw:: latex + + \clearpage + +.. _vpp_known_issues: + +Known Issues +------------ + +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.
