VPP PERFORMANCE TESTS - **Intel Xeon 2n-skx, 3n-skx 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), done as part of updating Ubuntu 18.04 LTS kernel - version. Tested VPP and DPDK applications (L3fwd) are affected. - Skx test data will be added in subsequent maintenance report - version(s) once the issue is resolved. See - :ref:`vpp_known_issues`. + is provided using a different CSIT test environment compared to + CSIT-1908.1 and CSIT-1908. The changes were applied during the + CSIT-2001 development cycle. + + - 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 VPP code changes from + v19.08.1 to v19.08.2, both have been tested in CSIT + environment ver. 2. 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, after resolving the issue of lower - performance and behaviour inconsistency of these systems due to - the Linux kernel driven upgrade of processor microcode packages - to 0x500002c. The resolution is to use latest SuperMicro BIOS 3.2 - (for X11DPG-QT motherboards used) that upgrades processor - microcode to 0x500002c, AND NOT kernel provided ucode package as - it does put system into sub-optimal state. Subset of 2n-clx VPP - tests are failing due to clx system behaviour change: i) all ip4 - tests with xxv710 and avf driver and ii) some cx556a rdma tests. - 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. + included in this report. See :ref:`vpp_known_issues`. - - **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. + - **Service density 2n-skx tests**: Added higher NF density tests with + 802.1q (vlan) and VXLAN encapsulation from Traffic Generator. - - **Mellanox CX556A-EDAT tests**: Added tests with Mellanox - ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma - driver. + - **GBP tests**: Added GBP (Group Based Policy) routing test cases + with 802.1q (vlan) external traffic. - - **IPsec reconfiguration tests**: Added tests measuring the impact - of IPsec tunnels creations and removals. + - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and + scale test cases (Fortville NICs only). - - **Load Balancer tests**: Added VPP performance tests for Maglev, - L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode. + - **2n-skx tests**: Increased coverage of selected (COP, iACL, + Policer) test cases. -#. TEST FRAMEWORK + - **IPsec scale tests**: Added IPsec interface mode scale tests with + 1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 IPsec tunnels. + Removed DPDK backend dependency. Major IPsec test code + refactoring. - - **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. + - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP + performance tests using WRK generator talking to the VPP HTTP + static server plugin measuring connections per second and + requests per second. + + - **Changed methodology of dot1q tests in 2-Node testbeds**: dot1q + encapsulation is now used on both links of SUT. Previously dot1q + was used only on a single link with the other link carrying + untagged Ethernet frames. This change results in slightly lower + throughput in CSIT-1908 for all dot1q tests in all 2-Node + testbeds. + + - **KVM VM vhost-user tests**: completed move to Kernel-VM for all + tests. In addition to running DPDK Testpmd as VM workload, new + tests created with VPP as VM workload. VPP in VM is the same + version as the DUT VPP (acting as vSwitch) and its configuration + depends on the test type. For all L2 Ethernet Switching tests + it's vpp-l2xc (L2 cross-connect), for all IPv4 Routing tests it's + vpp-ip4 (VPP IPv4 routing). - - **CSIT PAPI support**: Finished conversion of CSIT VAT L1 keywords +#. TEST FRAMEWORK + + - **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 <https://jira.fd.io/browse/CSIT-1503>`_ and `TRex-519 - <https://trex-tgn.cisco.com/youtrack/issue/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. #.
