Release Notes
=============
Changes in |csit-release|
-------------------------
#. VPP PERFORMANCE TESTS
- **Enhanced and added VPP hoststack tests** to daily and weekly
trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3,
LD_PRELOAD NGINX.
- **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending
and report, in addition to RDMA_CORE ones that were already
there.
- **Jumbo frames tests** got fixed and re-added number of to report
coverage tests.
- **Intel Xeon SKX performance testbeds** got decommissioned and
removed from FD.io performance lab.
#. TEST FRAMEWORK
- **CSIT test environment** version has not changed from ver. 11 used
in previous release, see :ref:`test_environment_versioning`.
- **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
- `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 `_

Issues reported in previous releases which still affect the current results.
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| # | JiraID | Issue Description |
+====+=========================================+===========================================================================================================+
| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
| | `_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 2 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
| | `_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
| | `_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 3 | `CSIT-1798 | Investigate why vhost with testpmd in VM has two-band structure. |
| | `_ | Probably QEMU not allocating memory on the correct NUMA socket. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 4 | `CSIT-1800 | All Geneve L3 mode scale tests (1024 tunnels) are failing. |
| | `_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 5 | `CSIT-1801 | 9000B payload frames not forwarded over tunnels due to violating supported Max Frame Size (VxLAN, LISP, |
| | `_ | SRv6). |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 6 | `CSIT-1802 | all testbeds: AF-XDP - NDR tests failing from time to time. |

| | `_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 9 | `CSIT-1890 | 3n-alt: Tests failing until 40Ge Interface comes up. |
| | `_ | A consequence of CSIT-1848 link slowness persisting over to other job runs. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 10 | `CSIT-1849 | 2n-skx, 2n-clx, 2n-icx: UDP 16m TPUT tests fail to create all sessions. |
