-
-Changes in |csit-release|
--------------------------
-
-#. DPDK PERFORMANCE TESTS
-
- - **Intel Xeon 2n-skx, 3n-skx testbeds**: Testpmd and L3fwd
- performance test data is not included in this report version.
- This is due to the lower performance and behaviour inconsistency
- of these systems following the upgrade of processor microcode
- packages (skx ucode 0x2000064) as part of updating Ubuntu 18.04
- LTS kernel version. Tested VPP and DPDK applications (L3fwd) are
- affected. Skx test data will be added in subsequent maintenance
- report version(s) once the issue is resolved. See
- :ref:`dpdk_known_issues`.
-
- - **Intel Xeon 2n-clx testbeds**: DPDK performance test data is now
- included in this report, after resolving the issue of lower
- performance and behaviour inconsistency of these systems due to
- the Linux kernel driven upgrade of processor microcode packages
- to 0x500002c. The resolution is to use latest SuperMicro BIOS 3.2
- (for X11DPG-QT motherboards used) that upgrades processor
- microcode to 0x500002c, AND NOT kernel provided ucode package as
- it does put THE system into sub-optimal state.
-
-
-#. DPDK RELEASE VERSION CHANGE
-
- - |csit-release| tested |dpdk-release|, as used by |vpp-release|.
-
-#. TEST ENVIRONMENT
-
- - **TRex Fortville NIC Performance**: Received FVL fix from Intel
- resolving TRex low throughput issue. TRex per FVL NIC throughput
- increased from ~27 Mpps to the nominal ~37 Mpps. For detail see
- `CSIT-1503 <https://jira.fd.io/browse/CSIT-1503>`_ and `TRex-519
- <https://trex-tgn.cisco.com/youtrack/issue/trex-519>`_].
-
- - **New Intel Xeon Cascadelake Testbeds**: Added performance tests
- for 2-Node-Cascadelake (2n-clx) testbeds with x710, xxv710 and
- cx556a-edat NIC cards.
-
-..
- // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
- - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
- L3fwd performance test data is included in this report version,
- but it shows lower performance and behaviour inconsistency of
- these systems following the upgrade of processor microcode
- packages (skx ucode 0x2000064, clx ucode 0x500002c) as part of
- updating Ubuntu 18.04 LTS kernel version. Tested VPP and DPDK
- applications (L3fwd) are affected. Skx and Clx test data will be
- corrected in subsequent maintenance report version(s) once the
- issue is resolved. See :ref:`vpp_known_issues`.
