Changes in |csit-release|
-------------------------
-#. **VPP Performance Tests**
-
- - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
- configurable trial duration and number of consecutive executions.
- Coverage of MRR tests has been extended across more test
- scenarios. MRR tests are used for continuous performance trending
- and for comparison between VPP releases.
-
- - **MLRsearch Throughput**: MLRsearch algorithm has been introduced
- for all NDR and PDR throughput tests. All tests that previously
- used binary search got converted to MLRsearch. Coverage of NDR/PDR
- tests has been extended across more test scenarios.
-
- - **L2patch Tests**: Tests measure performance of VPP L2patch, the
- fastest L2 forwarding path implemented in VPP, that cross-links
- RX and TX of two physical interfaces.
-
- - **2-Node Tests**: A new baseline set of 2-node tests covering base
- ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake
- testbeds.
-
- - **Generated tests**: Simplified and unified test structure, semi-
- autogenerated by generator script. Test generator is currently
- able to create test combinations with various frame size and
- cores combinations. All existing test cases were converted to new
- format.
-
- - **Simultaneous Multi-Threading**: SMT-aware detection of server
- processor operation mode (HyperThreading enabled/disabled) with
- associated compute resource configuration including thread
- affinity, number of Rx queues and DPDK I/O mbufs. Tests are
- automatically tagged during execution to indicate executed thread
- configuration.
-
- - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node
- physical testbed topologies based on the new SuperMirco servers
- each with two Intel Xeon Skylake Platinum processors. Full
- Ansible playbooks refactor for quick server (re)installation and
- reference pointers of configuration.
-
-#. **Presentation and Analytics Layer**
-
- - **Performance trending**: Further improved continuous performance
- trending with anomaly detection and analysis.
-
-#. **Test Framework Optimizations**
+#. VPP PERFORMANCE TESTS
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.
-
-Performance Changes
--------------------
-
-Relative performance changes in measured NDR, PDR and MRR packet
-throughput in |csit-release| are calculated against the test results
-from |csit-release-1| report, for tests running on 3-Node Intel Xeon
-Haswell testbeds (3n-hsw) in 1-core, 2-core and 4-core (MRR only)
-configurations.
+ - CSIT test environment is versioned, see
+ :ref:`test_environment_versioning`.
-Listed mean and standard deviation values are computed based on a series
-of the same tests executed against respective VPP releases to verify
-test results repeatability, with percentage change calculated for mean
-values. Note that the standard deviation is quite high for a small
-number of packet throughput tests, what indicates poor test results
-repeatability and makes the relative change of mean throughput value not
-fully representative for these tests. The root causes behind poor
-results repeatability vary between the test cases.
-
-NDR Changes
-~~~~~~~~~~~
+ - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
+ See :ref:`geneve_methodology` for more details.
-NDR throughput changes between releases are available in CSV and pretty
-ASCII formats:
- - `CSV 1t1c NDR changes <../_static/vpp/performance-changes-1t1c-ndr.csv>`_,
- - `CSV 2t2c NDR changes <../_static/vpp/performance-changes-2t2c-ndr.csv>`_,

- - `ASCII 2t2c NDR changes <../_static/vpp/performance-changes-2t2c-ndr.txt>`_.
+ - **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.
-.. note::
- Test results have been generated by
- `FD.io test executor vpp performance job 3n-hsw`_,
- with RF result
- files csit-vpp-perf-|srelease|-\*.zip
- `archived here <../_static/archive/>`_.
+ - **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.
-PDR Changes
-~~~~~~~~~~~
+ - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled
+ in ipsec suites.
-PDR throughput changes between releases are available in CSV and pretty
-ASCII formats:

+ - **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.
-.. note::
+ - **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 results have been generated by
- `FD.io test executor vpp performance job 3n-hsw`_,
- with RF result
- files csit-vpp-perf-|srelease|-\*.zip
- `archived here <../_static/archive/>`_.

-MRR Changes
-~~~~~~~~~~~
+ - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode.
-MRR throughput changes between releases are available in CSV and pretty
-ASCII formats:
+ - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
+ still used in CSIT for all VPP scale tests. See known issues below.

-Throughput Trending
--------------------
-
-In addition to reporting throughput changes between VPP releases, CSIT
-provides continuous performance trending for VPP master branch:
-
-#. `VPP Performance Dashboard <https://docs.fd.io/csit/master/trending/introduction/index.html>`_
- - per VPP test case throughput trend, trend compliance and summary of
- detected anomalies.
-
-#. `Trending Methodology <https://docs.fd.io/csit/master/trending/methodology/index.html>`_
- - throughput test metrics, trend calculations and anomaly
- classification (progression, regression, outlier).
-
-#. `Trendline Graphs <https://docs.fd.io/csit/master/trending/trending/index.html>`_
- - per VPP build MRR throughput measurements against the trendline
- with anomaly highlights, with associated CSIT test jobs.

++====+=========================================+===========================================================================================================+
+| 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. |

+| 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. |
