   7 #. VPP PERFORMANCE TESTS
   8
   9    - **Service density 2n-skx tests**: Added higher NF density tests with
  10      802.1q (vlan) and VXLAN encapsulation from Traffic Generator.
  11
  12    - **GBP tests**: Added GBP (Group Based Policy) routing test cases
  13      with 802.1q (vlan) external traffic.
  14
  15    - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and
  16      scale test cases (Fortville NICs only).
  17
  18    - **2n-skx tests**: Increased coverage of selected (COP, iACL,
  19      Policer) test cases.
  20
  21    - **IPsec scale tests**: Added IPsec interface mode scale tests with
  22      1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 IPsec tunnels.
  23      Removed DPDK backend dependency. Major IPsec test code
  24      refactoring.
  25
  26    - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP
  27      performance tests using WRK generator talking to the VPP HTTP
  28      static server plugin measuring connections per second and
  29      requests per second.
  30
  31    - **Changed methodology of dot1q tests in 2-Node testbeds**: dot1q
  32      encapsulation is now used on both links of SUT. Previously dot1q
  33      was used only on a single link with the other link carrying
  34      untagged Ethernet frames. This change results in slightly lower
  35      throughput in CSIT-1908 for all dot1q tests in all 2-Node
  36      testbeds.
  37
  38    - **KVM VM vhost-user tests**: completed move to Kernel-VM for all
  39      tests. In addition to running DPDK Testpmd as VM workload, new
  40      tests created with VPP as VM workload. VPP in VM is the same
  41      version as the DUT VPP (acting as vSwitch) and its configuration
  42      depends on the test type. For all L2 Ethernet Switching tests
  43      it's vpp-l2xc (L2 cross-connect), for all IPv4 Routing tests it's
  44      vpp-ip4 (VPP IPv4 routing).
  45
  46 #. TEST FRAMEWORK
  47
  48    - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords
  49      to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI).
  50      Redesign of key components of PAPI Socket Executor and PAPI
  51      history. Due to issues with PAPI performance, VAT is still used
  52      in CSIT for all VPP scale tests. See known issues below.
  53
  54    - **General Code Housekeeping**: Ongoing RF keywords optimizations,
  55      removal of redundant RF keywords and aligning of suite/test
  56      setup/teardowns.
  57
  58
  59 #. PRESENTATION AND ANALYTICS LAYER
  60
  61    - **Graphs Layout Improvements**: Improved performance graphs layout
  62      for better readibility and maintenance: test grouping, axis
  63      labels, descriptions, other informative decoration.

 100 | 8  | `CSIT-1591                              | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much  |
 101 |    | <https://jira.fd.io/browse/CSIT-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side.                                     |

 107 |    | <https://jira.fd.io/browse/CSIT-1592>`_ | tested VAT/CLI where memif zero-copy was enabled by default. Needs to be fixed in VPP.                   |
 108 |    +-----------------------------------------+                                                                                                          |
 109 |    | `VPP-1764                               |                                                                                                          |
