7 #. DPDK PERFORMANCE TESTS
9 - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
10 L3fwd performance test data is not included in this report
11 version. This is due to the lower performance and behaviour
12 inconsistency of these systems following the upgrade of processor
13 microcode packages (skx ucode 0x2000064, clx ucode 0x500002c) as
14 part of updating Ubuntu 18.04 LTS kernel version. Tested VPP and
15 DPDK applications (L3fwd) are affected. Skx and Clx test data
16 will be added in subsequent maintenance report version(s) once
17 the issue is resolved. See :ref:`dpdk_known_issues`.
20 // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
21 - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
22 L3fwd performance test data is included in this report version,
23 but it shows lower performance and behaviour inconsistency of
24 these systems following the upgrade of processor microcode
25 packages (skx ucode 0x2000064, clx ucode 0x500002c) as part of
26 updating Ubuntu 18.04 LTS kernel version. Tested VPP and DPDK
27 applications (L3fwd) are affected. Skx and Clx test data will be
28 corrected in subsequent maintenance report version(s) once the
29 issue is resolved. See :ref:`vpp_known_issues`.
