4 Changes in |csit-release|
5 -------------------------
7 #. DPDK PERFORMANCE TESTS
9 - **Intel Xeon 2n-skx, 3n-skx testbeds**: Testpmd and L3fwd
10 performance test data is not included in this report version.
11 This is due to the lower performance and behaviour inconsistency
12 of these systems following the upgrade of processor microcode
13 packages (skx ucode 0x2000064) as part of updating Ubuntu 18.04
14 LTS kernel version. Tested VPP and DPDK applications (L3fwd) are
15 affected. Skx test data will be added in subsequent maintenance
16 report version(s) once the issue is resolved. See
17 :ref:`dpdk_known_issues`.
19 - **Intel Xeon 2n-clx testbeds**: DPDK performance test data is now
20 included in this report, after resolving the issue of lower
21 performance and behaviour inconsistency of these systems due to
22 the Linux kernel driven upgrade of processor microcode packages
23 to 0x500002c. The resolution is to use latest SuperMicro BIOS 3.2
24 (for X11DPG-QT motherboards used) that upgrades processor
25 microcode to 0x500002c, AND NOT kernel provided ucode package as
26 it does put THE system into sub-optimal state.
29 #. DPDK RELEASE VERSION CHANGE
31 - |csit-release| tested |dpdk-release|, as used by |vpp-release|.
35 - **TRex Fortville NIC Performance**: Received FVL fix from Intel
36 resolving TRex low throughput issue. TRex per FVL NIC throughput
37 increased from ~27 Mpps to the nominal ~37 Mpps. For detail see
38 `CSIT-1503 <https://jira.fd.io/browse/CSIT-1503>`_ and `TRex-519
39 <https://trex-tgn.cisco.com/youtrack/issue/trex-519>`_].
41 - **New Intel Xeon Cascadelake Testbeds**: Added performance tests
42 for 2-Node-Cascadelake (2n-clx) testbeds with x710, xxv710 and
43 cx556a-edat NIC cards.
46 // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
47 - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
48 L3fwd performance test data is included in this report version,
49 but it shows lower performance and behaviour inconsistency of
50 these systems following the upgrade of processor microcode
51 packages (skx ucode 0x2000064, clx ucode 0x500002c) as part of
52 updating Ubuntu 18.04 LTS kernel version. Tested VPP and DPDK
53 applications (L3fwd) are affected. Skx and Clx test data will be
54 corrected in subsequent maintenance report version(s) once the
55 issue is resolved. See :ref:`vpp_known_issues`.
