Release Notes
=============
@@ -6,70 +8,40 @@ Changes in |csit-release|
#. VPP PERFORMANCE TESTS
- - **BMRR Throughput**: MRR (Maximum Receive Rate) test code has been
- updated with a configurable burst MRR parameters: trial duration
- and number of trials in a single burst. Enables a new Burst MRR
- (BMRR for short) methodology for more precise performance
- trending. See updated :ref:`performance_test_methodology` section
- for more details.
-
- - **2n-skx tests**: Added performamce tests for 2n-skx (2-Node Xeon
- Skylake) testbeds: focus on baseline and scale tests, including
- VM vhost and Container memif tests.
-
- - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon
- Skylake) testbeds: VM vhost and Container memif tests.
+ - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
+ Atom processors), to later replace 3n-dnv and 2n-dnv (3 and 2 Node
+ Denverton) testbeds.
- - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with
- dot1q and VPP L2BD.
+ - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
+ testbeds.
- - **AVF Driver Tests**: Added performamce tests for i40e AVF driver
- on VPP, no DPDK required.
+ - **Added Wireguard tests** for VPP software path (3n-icx, 3n-snr
+ testbeds) and with built-in HW crypto QAT device (3n-snr testbed
+ only).
- - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards.
-
- - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests
- to daily trending.
+ - **Reduction of tests**: Removed certain test variations executed
+ iteratively for the report (as well as in daily and weekly
+ trending) due to physical testbeds overload.
#. TEST FRAMEWORK
- - **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:`performance_test_methodology` section for more details.
-
- - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily
- trending.
+ - **CSIT test environment** version has been updated to ver. 11, see
+ :ref:`test_environment_versioning`.
- - **Per VPP Patch Performance Checks**: Per VPP gerrit patch vs.
- parent performance tests, anomaly detection and no verify voting
- (-1/0/+1) yet. Manual trigger only. Not "marketed" to FD.io
- community yet to avoid excessive LFN FD.io physical performance
- testbed blocking.
+ - **TCP tput profiles** have to be changed, as newer TRex versions
+ are not deterministic enough when deciding when to send an ACK.
- - **Patch-on-Patch Infra**: Added capability to run performance tests
- using CSIT gerrit patch code testing VPP gerrit patch code, i.e.
- before any VPP and/or CSIT code is merged into git branch.
+ - **CSIT PAPI support**: Due to issues with PAPI performance, and
+ deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
+ tests. See :ref:`vpp_known_issues`.
- - **CSIT PAPI Support**: Initial implementation of PAPI L1 KWs in
- CSIT using VPP Python bindings. Required for migraing away from
- VAT. Very few L1 KWs implemented ("show version", "show
- interfaces").
-
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.
+ - **General Code Housekeeping**: Ongoing code optimizations 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. Master report
- generated. 744 graphs(!)
-
-
- - **Performance Trending**: Further improvements of continuous
- performance trending, anomaly detection and analysis.
+ - **C-Dash** `performance dashboard `_ got updated UI and
+ updated backend increasing its performance and robustness.

++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| # | JiraID | Issue Description |
++====+=========================================+===========================================================================================================+
+| 1 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
+| | `_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ Currently, the time critical code uses VAT running large files with exec statements and CLI commands. |
+| | `VPP-1763 | Still, we needed to reduce the number of scale tests run to keep overall duration reasonable. |
+| | `_ | More improvements needed to achieve sufficient configuration speed. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | `_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | `_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
+| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
+| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1799 | All NAT44-ED 16M scale tests fail while setting NAT44 address range. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 5 | `CSIT-1800 | All Geneve L3 mode scale tests (1024 tunnels) are failing. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 6 | `CSIT-1801 | 9000B payload frames not forwarded over tunnels due to violating supported Max Frame Size (VxLAN, LISP, |
+| | `_ | SRv6). |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 7 | `CSIT-1802 | AF-XDP - NDR tests failing from time to time. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 8 | `CSIT-1804 | All testbeds: NDR tests failing from time to time. |

+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 10 | `CSIT-1827 | 3n-icx, 3n-skx: all AVF crypto tests sporadically fail. 1518B with no traffic, IMIX with excessive |
+| | `_ | packet loss. |

++----+-----------------------------------------+-------------------------------------------------------------------------------------+
+| # | JiraID | Issue Description |
++====+=========================================+=====================================================================================+
+| 1 | `VPP-2030 | regression: ip6base on ICX around 2022-03-23 |
+| | `_ | "Loads blocked due to overlapping with a preceding store that cannot be forwarded." |
+| | | started happening in ip6-lookup graph node. |
++----+-----------------------------------------+-------------------------------------------------------------------------------------+
+| 2 | `CSIT-1852 | 2n-zn2 mellanox performance cap |
+| | `_ | Old issue, only now distinguished from CSIT-1751. |
+| | | This testbed+nic combination is capped below 28 Mpps, cause not identified yet. |
++----+-----------------------------------------+-------------------------------------------------------------------------------------+
+| 3 | `CSIT-1853 | trending regression: nat44ed cps around 2202-04-01 |
+| | `_ | VPP change added more computation to slow path (in order to support multiple VRFs). |
+| | | Not clear if the VPP implementation is optimized enough. |
