VPP PERFORMANCE TESTS - - **Service density 2n-skx tests**: Added higher NF density tests with two - NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now - used as a VNF payload similar to CNF tests. - - - **Soak Tests**: Optimized performamce soak tests framework - code for extended time duration tests and throughput discovery - at given PLR and at give total test time e.g. minutes, hours, - days, weeks. See updated - :ref:`test_methodology` section for more details. + - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP test data is + not included in this report version. This is due to performance + and behaviour inconsistency following the upgrade to the latest + Ubuntu 18.04 LTS kernel version (4.15.0-72-generic) and + associated microcode packages (skx ucode 0x2000064, clx ucode + 0x500002c). 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. + + - **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. + + - **Load Balancer tests**: Added VPP performance tests for Maglev, + L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode. #. TEST FRAMEWORK - - **Qemu code refactor**: Complete code refactor of the key components of - QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added - implementation of kernel-image-kvm based VM replacing the previously used - NestedVM images. Added ability to run VPP as a payload in VNF. + - **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**: Continued conversion of CSIT VAT L1 keywords to - PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components - of PAPI Executor and PAPI history. + - **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. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. + - **Test Suite Generator**: Added capability to generate suites for + different drivers per NIC model including DPDK, AVF, RDMA. + Extended coverage for all tests. - - **Test suite generator**: Added capability to generate suites for - different NIC models as well as throughput search algorithm types. Uses - base tests suites as source. + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords and aligning of suite/test + setup/teardowns. - - **TOX verification**: Added verifications for test suite generator. #. PRESENTATION AND ANALYTICS LAYER - - **Graphs Layout Improvements**: Improved performance graphs layout + - **Graphs layout improvements**: Improved performance graphs layout for better readibility and maintenance: test grouping, axis labels, descriptions, other informative decoration. -.. - #. MISCELLANEOUS - - - **2n-dnv Tests (3rd Party)**: Published performance tests for 2n- - dnv (2-Node Atom Denverton) from 3rd party testbeds running FD.io - |csit-release| automated testing code. - Only graphs for Packet Throughput and Speedup Multi-core and not - for Packet Latency were published as there are no results for Packet - Latency available. + - **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 @@ -63,24 +85,35 @@ 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.
