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 <http://csit.fd.io/>`_ 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 <https://csit.fd.io/report/#eNrdVcluwjAQ_Zr0ggbZDml64QDkP5BxhhJlwYxNVPr1OAhpYiGO7cEHb3pv1qeRnT8T7h1266zYZuU2U2VThy3LN4twUOdULhSM1oLKl-FG2KF2CGqAxvyAFOIblZX4JYW5gB6P0NgVfK4OIA2gP02vsA6Tja1pcq12T9cvcRitr57RED1CRiQGo7SYZk-3GeddsszXhJoNQsYMeXSzZOKamHUk3aNrfpGpoQuMm9BohqSJ_fubnaHPRpXVg_F3qjijO1RCtEBDnZo8UXFJ6NQmKlGbgjp9ujPU_8cEFdXHcKb-8Q8V1R2PI8PX>`_
