#. VPP PERFORMANCE TESTS
- - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP 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), done 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:`vpp_known_issues`.

+ - **Intel Xeon 2n-clx testbeds**: VPP 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 system into sub-optimal state. Subset of 2n-clx VPP
+ tests are failing due to clx system behaviour change: i) all ip4
+ tests with xxv710 and avf driver and ii) some cx556a rdma tests.
+ See :ref:`vpp_known_issues`.
- **Service density 2n-skx tests**: Added new NF density tests with
IPsec encryption between DUTs.

generator (Intel Fortville NICs only).
- - **Hoststack TCP/IP tests**: Major refactor of VPP Hoststack TCP/IP

performance tests using WRK generator talking to the VPP HTTP
static server plugin measuring connections per second and
- requests per second. Added iperf3 tests with LDPreload.
+ requests per second. Added new iperf3 with LDPreload tests,
+ iperf3/LDPreload tests with packet loss induced via the VPP NSIM
+ (Network Simulator) plugin, and QUIC/UDP/IP transport tests.
+ All of the new tests measure goodput through the VPP Hoststack
+ from client to server.
- **Latency HDRHistogram**: Added High Dynamic Range Histogram
latency measurements based on the new capability in TRex traffic
generator. HDRH latency data presented in latency packet
percentile graphs and in detailed results tables.
- - **Mellanox MCX556A-EDAT tests**: Added tests with Mellanox
+ - **Mellanox CX556A-EDAT tests**: Added tests with Mellanox
ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma
driver.
- **Load Balancer tests**: Added VPP performance tests for Maglev,
L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode.

#. TEST FRAMEWORK
- **CSIT Python3 support**: Full migration of CSIT from Python2.7 to
removal of redundant RF keywords and aligning of suite/test
setup/teardowns.
+#. 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.
