- - **BMRR Throughput**: MRR (Maximum Receive Rate) test code has been
- updated with a configurable burst MRR parameters: trial duration
- and number of trials in a single burst. Enables a new Burst MRR
- (BMRR for short) methodology for more precise performance
- trending. See updated :ref:`test_methodology` section
- for more details.
-
- - **2n-skx tests**: Added performamce tests for 2n-skx (2-Node Xeon
- Skylake) testbeds: focus on baseline and scale tests, including
- VM vhost and Container memif tests.
-
- - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon
- Skylake) testbeds: VM vhost and Container memif tests.
-
- - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with
- dot1q and VPP L2BD.
-
- - **AVF Driver Tests**: Added performamce tests for i40e AVF driver
- on VPP, no DPDK required.
-
- - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards.
-
- - **VM Vhost Virtio Params Combinations**: Added performance tests
- for VM vhost with different virtio parameters combinations:
- indirect buffers, mergeable buffers.
-
- - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests
- to daily trending.
+ - **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`.
+
+ - **Service density 2n-skx tests**: Added new NF density tests with
+ IPsec encryption between DUTs.
+
+ - **AVF tests**: Full test coveraged based on code changes in CSIT
+ core layer (driver/interface awareness) and generated by suite
+ 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.
+
+ - **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
+ ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma
+ driver.
+
+ - **IPsec reconfiguration tests**: Added tests measuring the impact
+ of IPsec tunnels creations and removals.
+
+ - **Load Balancer tests**: Added VPP performance tests for Maglev,
+ L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode.

+ - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP performance
