- - **Intel Xeon 2n-skx, 3n-skx 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), done as part of updating Ubuntu 18.04 LTS kernel
- version. Tested VPP and DPDK applications (L3fwd) are affected.
- Skx 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.
-
- - **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 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 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 CX556A-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.
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
+
+ - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
+ See :ref:`geneve_methodology` for more details.
+
+
+ - **GSO tests**: Added VPP performance tests for GSOtap and GSOvirtio.
+ All tested topologies are compared with GSO enabled and disabled.
+ In |csit-release| there is only 1t1c tests running.
+ See :ref:`gso_methodology` for more details.
