#. VPP PERFORMANCE TESTS
- - **Intel Xeon Ice Lake**: Added initial test data for these
- platforms. Current CSIT-2106 report data for Intel Xeon Ice Lake
- comes from an external source (Intel labs running CSIT code on
- "8360Y D Stepping" and "6338N" processors). For details about the
- physical setup see :ref:`tested_physical_topologies`. Tested
- VPP and CSIT versions are pre-release, VPP
- 21.06-rc0~779-gd640ae52f.
-
- - **MLRsearch improvements**: Added support for multiple packet
- throughput rates in a single search, each rate is associated
- with a distinct Packet Loss Ratio (PLR) criterion. Previously
- only Non Drop Rate (NDR) (PLR=0) and single Partial Drop Rate
- (PDR) (PLR<0.5%) were supported. Implemented number of
- optimizations improving rate discovery efficiency.
-
- - **Reduction of tests**: Removed obsolete VPP use cases and
- superfluous test combinations from continuous and report test
- executions, including:
-
- - All vts tests, obsolete use cases.
- - dot1q tests apart from dot1q-l2bd, superfluous combinations.
- - -100flows, -100kflows in all acl tests.
- - nat44 tests
-
- - -pps tests, replaced by -tput tests.
- - h1-p1-s1 single session tests, unessential combination.
- - h4096-p63-s258048 tests, unessential scale combination.
-
- - ipsec tests
-
- - ethip4ipsectptlispgpe.
- - policy-aes128gcm.
- - policy-aes128cbc-hmac256sha.
- - policy-aes128cbc-hmac512sha.
- - int-aes128cbc-hmac256sha.
- - scale of
-
- - 400tnlsw.
- - 5000tnlsw.
- - 20000tnlsw.
- - 60000tnlsw.
+ - **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.
+
+ - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
+ testbeds.
+
+ - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
+ testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
+ only).
+
+ - **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
- - **CSIT test environment** version has been updated to ver. 8, see
+ - **CSIT test environment** version has been updated to ver. 11, see
:ref:`test_environment_versioning`.
- - **CSIT in AWS environment**: Added CSIT support for AWS c5n
- instances environment.
+ - **TCP tput profiles** have to be changed, as newer TRex versions
+ are not deterministic enough when deciding when to send an ACK.
- - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
- still used in CSIT for all VPP scale tests. See known issues
- below.
+ - **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`.
- **General Code Housekeeping**: Ongoing code optimizations and bug
fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs improvements**: Updated Packet Latency graphs,
- see :ref:`latency_methodology`.
+ - **C-Dash** `performance dashboard `_ got updated UI and
+ updated backend increasing its performance and robustness.

++====+=========================================+===========================================================================================================+
+| 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. |
-| +-----------------------------------------+ 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 |
-| | `_ | too long. |
+| +-----------------------------------------+ 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-1789 | AVF driver does not perform RSS in a deterministic way. |
-| | `_ | This increases standard deviation of tests with small number of flows (mainly ipsec). |
+| 4 | `CSIT-1799 | All NAT44-ED 16M sessions CPS scale tests fail while setting NAT44 address range. |
+| | `_ | |

-| 5 | `CSIT-1790 | Broken TRex latency measurements with TRex v2.88, DPDK 21.02 and FVL FW 6.01. |
-| | `_ | High latency O(5msec) for all VPP and testpmd/l3fwd test cases for FVL NICs with FW 6.01. |
