#. VPP PERFORMANCE TESTS
- - **Service density 2n-skx tests**: Added higher NF density tests with
- IPSec encencryption between DUTs.
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
- - **AVF tests**: Full test coveraged based on code changes in CSIT core
- layer (driver/interface awareness) and generated by suite generator
- (Fortville NICs only).
+ - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
+ See :ref:`geneve_methodology` for more details.
- - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP
- performance tests using WRK generator talking to the VPP HTTP
- static server plugin measuring connections per second and
- requests per second.
-#. TEST FRAMEWORK
+ - **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.
- - **CSIT Python3 Support**: Full migration of CSIT from Python2.7 to
- Python3.6. This change includes library migration, PIP dependency upgrade,
- CSIT container images, infrastructure packages ugrade/installation.
+ - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled
+ in ipsec suites.
- - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords
- to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI).
- Redesign of key components of PAPI Socket Executor and PAPI
- history. Due to issues with PAPI performance, VAT is still used
- in CSIT for all VPP scale tests. See known issues below.
+ - **Randomized profiles**: Improved repeatability and cycle length.
+ For details, see :ref:`packet_flow_ordering`.
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords and aligning of suite/test
- setup/teardowns.
+ - **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 Layout Improvements**: Improved performance graphs layout
- for better readibility and maintenance: test grouping, axis
- labels, descriptions, other informative decoration.
+ - **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-1498 | Memif tests are sporadically failing on initialization of memif connection. |
-| | <https://jira.fd.io/browse/CSIT-1498>`_ | |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 4 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. |
-| | <https://jira.fd.io/browse/VPP-1677>`_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 5 | `CSIT-1591 | 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-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
-| +-----------------------------------------+ |
-| | `VPP-1763 | |
-| | <https://jira.fd.io/browse/VPP-1763>`_ | |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 6 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. |
-| | <https://jira.fd.io/browse/VPP-1675>`_ | Reason: chained buffers are not supported. |
-+----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
-| 7 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |
-| | <https://jira.fd.io/browse/CSIT-1593>`_ | |

+| 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. |
