#. 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.
+ - **Enhanced and added VPP hoststack tests** to daily and weekly
+ trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3,
+ LD_PRELOAD NGINX.
- - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
- testbeds.
+ - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending
+ and report, in addition to RDMA_CORE ones that were already
+ there.
- - **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.
+ - **Jumbo frames tests** got fixed and re-added number of to report
+ coverage tests.
-#. TEST FRAMEWORK
+ - **Intel Xeon SKX performance testbeds** got decommissioned and
+ removed from FD.io performance lab.
- - **CSIT test environment** version has been updated to ver. 11, see
- :ref:`test_environment_versioning`.
+#. TEST FRAMEWORK
- - **TCP tput profiles** have to be changed, as newer TRex versions
- are not deterministic enough when deciding when to send an ACK.
+ - **CSIT test environment** version has not changed from ver. 11 used
+ in previous release, see :ref:`test_environment_versioning`.
- - **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`.
+ - **CSIT PAPI optimizations for scale** got applied improving PAPI
+ programming speed especially for large scale tests. VAT has been
+ now completely deprecated from CSIT.
- **General Code Housekeeping**: Ongoing code optimizations and bug
fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **C-Dash** `performance dashboard `_ got updated UI and
- updated backend increasing its performance and robustness.
+ - `Performance dashboard `_ got updated with
+ addition of VPP telemetry trending across all VPP tests. A number
+ of code and AWS resource usage optimizations got applied to the
+ data processing pipeline and UI frontend and backend.
+
+ - Examples of release iterative data visualisation:
+
+ - `Packet throughput 2n-icx-e810cq-ip4-base-scale-pdr `_
+ - `Speedup Multi-Core throughput graph for 2n-icx-e810cq-ip4-base-pdr `_
+ - `MRR, NDR and PDR comparison for 2n-icx-e810cq-ip4-base `_
+ - `Normalized throughput architecture comparison for 2n-[icx|clx]-e810cq-ip4-base-pdr `_
+ - `NICs comparison for 2n-icx-ip4-base-pdr `_
