-
-Changes in |csit-release|
--------------------------
-
-#. VPP PERFORMANCE TESTS
-
- - 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.
-
-
- - **NAT44 tests**: Added new test type, pure throughput tests.
- They are similar to PPS tests, but they employ ramp-up trials
- to ensure all sessions are created (and not timing out)
- for performance trials.
-
- - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled
- in ipsec suites.
-
- - **Randomized profiles**: Improved repeatability and cycle length.
- For details, see :ref:`packet_flow_ordering`.
-
- - **Arm 2n-tx2 testbed**: New physical testbed type installed in
- FD.io CSIT, with VPP and DPDK performance data added to CSIT
- trending and this report.
-
- - **Framework speedup**: Shortened overall test job duration
- by using a different test selection mechanism (using --test
- instead of --include) and by avoiding unnecessary PAPI reconnects.
-
-#. TEST FRAMEWORK
-
- - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode.
-
- - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
- still used in CSIT for all VPP scale tests. See known issues below.
-
- - **General Code Housekeeping**: Ongoing code optimizations,
- speed ups and bug fixes.
-
-#. PRESENTATION AND ANALYTICS LAYER
-
- - **Graphs improvements**: Updated Packet Latency graphs,
- see :ref:`latency_methodology`.

-List of known issues in |csit-release| for VPP performance tests:
-
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| # | JiraID | Issue Description |
-+====+=========================================+===========================================================================================================+
-| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
-| | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
-| | <https://jira.fd.io/browse/VPP-662>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 3 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
-| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 4 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
-| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
-| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
-| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
-| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `VPP-1934 | [i40e] Interfaces are not brought up from carrier-down. |
-| | <https://jira.fd.io/browse/VPP-1934>`_ | In case of i40e -based interface (e.g Intel x700 series NIC) is bound to kernel driver (i40e) and is in |
-| | | state "no-carrier" (<NO-CARRIER,BROADCAST,MULTICAST,UP>) because previously it was disabled via |
-| | | "I40E_AQ_PHY_LINK_ENABLED" call, then VPP during initialization of AVF interface is not re-enabling |
-| | | interface link via i40e driver to up. |
-| | | CSIT implemented `workaround for AVF interface <https://gerrit.fd.io/r/c/csit/+/29086>`_ until fixed. |

-| # | JiraID | Issue Description |

-| 1 | `VPP-1972 | One VPP change has decreased performance of NAT44ed processing, both slow path and fast path. |
