VPP PERFORMANCE TESTS + + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. + + - To identify performance changes due to VPP code changes from + v20.05.0 to v20.09.0, both have been tested in CSIT environment + ver. 5 and compared against each other. All substantial + progressions has been marked up with RCA analysis. See + :ref:`vpp_compare_current_vs_previous_release` and + :ref:`vpp_known_issues`. + + - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels. + + - See :ref:`geneve_methodology` for more details. + + - **NAT44 tests**: Adapted existing and added new tests. + + - Refactored NAT44 deterministic mode (nat44det) tests to use separate + det44 vpp plugin and to use the same scheme of inside and outside + addresses and ports, as used in new NAT44 endpoint-dependent mode tests. + + - Added new NAT44 endpoint-depended mode uni-directional (nat44ed-udir) + tests that measure packet throughput in one direction with usage of TRex + in stateless mode. + + - Added new NAT44 endpoint-dependent mode CPS tests that measure + connections per second with usage of TRex in stateful mode. + UPD packet size is 64 bytes. Size of TCP control packets + is not configurable, please ignore the -64b- part of test names. + + - Added new NAT44 endpoint-dependent mode PPS tests that measure + packets per second (control and data together) with usage of TRex + in stateful mode. UPD packet size is 64 bytes. Size of TCP + data packets is governed by the default MSS value, so most data packets + are 1460 bytes long, please ignore the -64b- part of test names. + + - See :ref:`nat44_methodology` for more details. + + - **IPSec async mode tests**: Added VPP performance tests for async crypto + engine. + + - **AMD 2n-zn2 testbed**: New physical testbed type installed in + FD.io CSIT, with VPP and DPDK performance data added to CSIT + trending and this report. + + - **AMD 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. + +#. TEST FRAMEWORK + + - **TRex ASTF**: Added capability to run TRex in advanced stateful mode. + + - **CSIT PAPI support**: 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 and aligning of suite/test + setup/teardowns. + + - **Intel E810CQ 100G NIC**: Added configuration for Intel E810CQ 100G NIC. + No tests run for this NIC as it is not present in FD.io CSIT lab yet. + +#.
