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. + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. -#. TEST FRAMEWORK + - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels. + See :ref:`geneve_methodology` for more details. + + + - **GSO tests**: Added VPP performance tests for GSOtap and GSOvirtio. + All tested topologies are compared with GSO enabled and disabled. + In |csit-release| there is only 1t1c tests running. + See :ref:`gso_methodology` for more details. + + + - **NAT44 tests**: Added new test type, pure throughput tests. + They are similar to PPS tests, but they employ ramp-up trials + to ensure all sessions are created (and not timing out) + for performance trials. - - **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. + - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled + in ipsec suites. - - **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. + - **Randomized profiles**: Improved repeatability and cycle length. + For details, see :ref:`packet_flow_ordering`. - - **Test Suite Generator**: Added capability to generate suites for - different drivers per NIC model including DPDK, AVF, RDMA. - Extended coverage for all tests. + - **Arm 2n-tx2 testbed**: New physical testbed type installed in + FD.io CSIT, with VPP and DPDK performance data added to CSIT + trending and this report. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords and aligning of suite/test - setup/teardowns. + - **Framework speedup**: Shortened overall test job duration + by using a different test selection mechanism (using --test + instead of --include) and by avoiding unnecessary PAPI reconnects. -#. TEST ENVIRONMENT +#. TEST FRAMEWORK + + - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode. - - **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 support**: Due to issues with PAPI performance, VAT is + still used in CSIT for all VPP scale tests.

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.
