   7 #. VPP PERFORMANCE TESTS
   8
   9    - **Service density 2n-skx tests**: Network Function Virtualization (NFV)
  10      service density tests focus on measuring total per server throughput at
  11      varied NFV service *packing* densities with vswitch providing host
  12      dataplane. The goal is to compare and contrast performance of a shared
  13      vswitch for different network topologies and virtualization technologies,
  14      and their impact on vswitch performance and efficiency in a range of NFV
  15      service configurations.
  16
  17    - **Experimental Soak Tests**: Added performamce soak tests framework
  18      code for extended time duration tests and throughput discovery
  19      at given PLR and at give total test time e.g. minutes, hours,
  20      days, weeks, months, years. See updated
  21      :ref:`test_methodology` section for more details.
  22
  23 #. TEST FRAMEWORK
  24
  25    - **Container code optimizations**: Optimized container library allows to
  26      run containre_memif tests faster.
  27
  28    - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to
  29      PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away
  30      from VAT.
  31
  32    - **General Code Housekeeping**: Ongoing RF keywords optimizations,
  33      removal of redundant RF keywords.
  34
  35 #. PRESENTATION AND ANALYTICS LAYER
  36
  37    - **Graphs Layout Improvements**: Improved performance graphs layout
  38      for better readibility and maintenance: test grouping, axis
  39      labels, descriptions, other informative decoration.
  40
  41 #. MISCELLANEOUS
  42
  43    - **2n-dnv Tests (3rd Party)**: Published performance tests for 2n-
  44      dnv (2-Node Atom Denverton) from 3rd party testbeds running FD.io
  45      |csit-release| automated testing code.
  46      Only graphs for Packet Throughput and Speedup Multi-core and not
  47      for Packet Latency were published as there are no results for Packet
  48      Latency available.
