+ // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
+ note::
+ L3fwd throughput drop in the current release in comparison to previous
+ releases **on Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: L3fwd
+ performance test data shows lower performance and behaviour
+ inconsistency of these systems following the recent 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`.
