- 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.
+ - **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.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs improvements**: Added possibility to use Gbps on Y-axis in
- Packet Throughput and Speedup Multi-Core graphs, added unidirectional
- mode to the Latency graphs.
+ - **Graphs improvements**: Updated Packet Latency graphs,
+ see :ref:`latency_methodology`.
