#. VPP PERFORMANCE TESTS
+ - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
+ Atom processors), to later replace 3n-dnv and 2n-dnv (3 and 2 Node
+ Denverton) testbeds.
+
+ - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
+ testbeds.
+
- **Reduction of tests**: Removed certain test variations executed
iteratively for the report (as well as in daily and weekly
trending) due to physical testbeds overload.
#. TEST FRAMEWORK
- - **Removed ASTF PPS tests**: They provide no real benefit
- compared to TPUT tests. The ip4base variants renamed to TPUT.
-
- - **Changed TCP TPUT profiles**: The previous ones were found to be faulty.
- The new ones do not use bursts of packets to avoid CSIT-1830 and CSIT-1846.
-
- - **CSIT test environment** version has been updated to ver. 10, see
+ - **CSIT test environment** version has been updated to ver. 11, see
:ref:`test_environment_versioning`.
+ - **TCP tput profiles** have to be changed, as newer TRex versions
+ are not deterministic enough when deciding when to send an ACK.
+
- **CSIT PAPI support**: Due to issues with PAPI performance, and
deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
tests. See :ref:`vpp_known_issues`.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs improvements**: Updated Packet Latency graphs,
- see :ref:`latency_methodology`.
+ - **`C-Dash <http://csit.fd.io/>`** performance dashboard got updated UI and
+ updated backend increasing its performance and robustness.
