   7 #. VPP PERFORMANCE TESTS
   8
   9    - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
  10      configurable trial duration and number of consecutive executions.
  11      Coverage of MRR tests has been extended across more test
  12      scenarios. MRR tests are used for continuous performance trending
  13      and for comparison between VPP releases.
  14
  15    - **MLRsearch Throughput**: MLRsearch algorithm has been introduced
  16      for all NDR and PDR throughput tests. All tests that previously
  17      used binary search got converted to MLRsearch. Coverage of NDR/PDR
  18      tests has been extended across more test scenarios.
  19
  20    - **L2patch Tests**: Tests measure performance of VPP L2patch, the
  21      fastest L2 forwarding path implemented in VPP, that cross-links
  22      RX and TX of two physical interfaces.
  23
  24    - **2-Node Tests**: A new baseline set of 2-node tests covering base
  25      ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake
  26      testbeds.
  27
  28    - **Generated tests**: Simplified and unified test structure, semi-
  29      autogenerated by generator script. Test generator is currently
  30      able to create test combinations with various frame size and
  31      cores combinations. All existing test cases were converted to new
  32      format.
  33
  34    - **Simultaneous Multi-Threading**: SMT-aware detection of server
  35      processor operation mode (HyperThreading enabled/disabled) with
  36      associated compute resource configuration including thread
  37      affinity, number of Rx queues and DPDK I/O mbufs. Tests are
  38      automatically tagged during execution to indicate executed thread
  39      configuration.
  40
  41    - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node
  42      physical testbed topologies based on the new SuperMirco servers
  43      each with two Intel Xeon Skylake Platinum processors. Full
  44      Ansible playbooks refactor for quick server (re)installation and
  45      reference pointers of configuration.
  46
  47 #. PRESENTATION AND ANALYTICS LAYER
  48
  49    - **Performance trending**: Further improvements of continuous
  50      performance trending, anomaly detection and analysis.
  51
  52 #. TEST FRAMEWORK OPTIMIZATIONS
  53
  54    - **General Code Housekeeping**: Ongoing RF keywords optimizations,
  55      removal of redundant RF keywords.
