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. + - **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. - - 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. + - **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. - - 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. + - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled + in ipsec suites. - - See :ref:`nat44_methodology` for more details. + - **Randomized profiles**: Improved repeatability and cycle length. + For details, see :ref:`packet_flow_ordering`. - - **IPSec async mode tests**: Added VPP performance tests for async crypto - engine. - - - **AMD 2n-zn2 testbed**: New physical testbed type installed in + - **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. + - **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 FRAMEWORK - - **TRex ASTF**: Added capability to run TRex in advanced stateful mode. + - **TRex ASTF**: Improved 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. + - **General Code Housekeeping**: Ongoing code optimizations, + speed ups and bug fixes. #.
