#. VPP PERFORMANCE TESTS
- - **Service density 2n-skx tests**: Network Function Virtualization (NFV)
- service density tests focus on measuring total per server throughput at
- varied NFV service *packing* densities with vswitch providing host
- dataplane. The goal is to compare and contrast performance of a shared
- vswitch for different network topologies and virtualization technologies,
- and their impact on vswitch performance and efficiency in a range of NFV
- service configurations.
-
- - **Experimental Soak Tests**: Added performamce soak tests framework
- code for extended time duration tests and throughput discovery
- at given PLR and at give total test time e.g. minutes, hours,
- days, weeks, months, years. See updated
- :ref:`test_methodology` section for more details.
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
-#. TEST FRAMEWORK
+ - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
- - **Container code optimizations**: Optimized container library allows to
- run containre_memif tests faster.
+ - See :ref:`geneve_methodology` for more details.
- - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to
- PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away
- from VAT.
+ - **NAT44 tests**: Adapted existing and added new tests.
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.
+ - Refactored NAT44 deterministic mode (nat44det) tests to use separate
+ det44 vpp plugin and to use the same scheme of inside and outside
+ addresses and ports, as used in new NAT44 endpoint-dependent mode tests.
-#. PRESENTATION AND ANALYTICS LAYER
+ - Added new NAT44 endpoint-depended mode uni-directional (nat44ed-udir)
+ tests that measure packet throughput in one direction with usage of TRex
+ in stateless mode.
+
+ - Added new NAT44 endpoint-dependent mode CPS tests that measure
+ connections per second with usage of TRex in stateful mode.
+ UPD packet size is 64 bytes. Size of TCP control packets
+ is not configurable, please ignore the -64b- part of test names.
+
+ - Added new NAT44 endpoint-dependent mode PPS tests that measure
+ packets per second (control and data together) with usage of TRex
+ in stateful mode. UPD packet size is 64 bytes. Size of TCP
+ data packets is governed by the default MSS value, so most data packets
+ are 1460 bytes long, please ignore the -64b- part of test names.
+
+ - See :ref:`nat44_methodology` for more details.
+
+ - **IPSec async mode tests**: Added VPP performance tests for async crypto
+ engine.
- - **Graphs Layout Improvements**: Improved performance graphs layout
- for better readibility and maintenance: test grouping, axis
- labels, descriptions, other informative decoration.
+ - **AMD 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.
-..
- #. MISCELLANEOUS
+#. 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
- - **3n-dnv Tests (3rd Party)**: Published performance tests for 3n-
- dnv (3-Node Atom Denverton) from 3rd party testbeds running FD.io
- |csit-release| automated testing code.
- Only graphs for Packet Throughput and Speedup Multi-core and not
- for Packet Latency were published as there are no results for Packet
- Latency available.
+ - **Graphs improvements**: Updated Packet Latency graphs,
+ see :ref:`latency_methodology`.

++====+=========================================+===========================================================================================================+

+| | <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 | `CSIT-1771 | IPv4 IPSEC 9000B packet tests had been failing when chained buffers were not supported. |
+| | <https://jira.fd.io/browse/CSIT-1771>`_ | This has been fixed on VPP side, but CSIT still needs to re-enable jumbo tests. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 6 | `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. |
