#. DPDK PERFORMANCE TESTS
- - **Intel Xeon 2n-skx, 3n-skx and 2n-clx 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, 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 added in subsequent maintenance report version(s) once
- the issue is resolved. See :ref:`dpdk_known_issues`.

+ 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.
