6 Changes in |csit-release|
7 -------------------------
9 #. VPP PERFORMANCE TESTS
11 - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
12 Atom processors), to later replace 3n-dnv and 2n-dnv (3 and 2 Node
15 - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
18 - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
19 testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
22 - **Reduction of tests**: Removed certain test variations executed
23 iteratively for the report (as well as in daily and weekly
24 trending) due to physical testbeds overload.
28 - **CSIT test environment** version has been updated to ver. 11, see
29 :ref:`test_environment_versioning`.
31 - **TCP tput profiles** have to be changed, as newer TRex versions
32 are not deterministic enough when deciding when to send an ACK.
34 - **CSIT PAPI support**: Due to issues with PAPI performance, and
35 deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
36 tests. See :ref:`vpp_known_issues`.
38 - **General Code Housekeeping**: Ongoing code optimizations and bug
41 #. PRESENTATION AND ANALYTICS LAYER
43 - **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
44 updated backend increasing its performance and robustness.

61 | 1 | `CSIT-1850 | 2n-dnv: sporadic 1518B tput tests failing to establish required sessions. |

64 | 2 | `CSIT-1864 | 2n-clx: half of the packets lost on PDR tests. |

67 | 3 | `CSIT-1871 | 3n-snr: 25Ge Interface goes down randomly. |

70 | 4 | `CSIT-1877 | 3n-alt, 3n-tsh: VM tests failing to boot VM. |

77 Issues reported in previous releases which still affect the current results.
79 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
80 | # | JiraID | Issue Description |
81 +====+=========================================+===========================================================================================================+
82 | 1 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
83 | | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
84 | +-----------------------------------------+ Currently, the time critical code uses VAT running large files with exec statements and CLI commands. |
85 | | `VPP-1763 | Still, we needed to reduce the number of scale tests run to keep overall duration reasonable. |
86 | | <https://jira.fd.io/browse/VPP-1763>`_ | More improvements needed to achieve sufficient configuration speed. |
87 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
88 | 2 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
89 | | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
90 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
91 | 3 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
92 | | <https://jira.fd.io/browse/CSIT-1785>`_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
93 | +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
94 | | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
95 | | <https://jira.fd.io/browse/VPP-1972>`_ | |
96 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
97 | 4 | `CSIT-1799 | All NAT44-ED 16M scale tests fail while setting NAT44 address range. |
98 | | <https://jira.fd.io/browse/CSIT-1799>`_ | |
99 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
100 | 5 | `CSIT-1800 | All Geneve L3 mode scale tests (1024 tunnels) are failing. |
101 | | <https://jira.fd.io/browse/CSIT-1800>`_ | |
102 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
103 | 6 | `CSIT-1801 | 9000B payload frames not forwarded over tunnels due to violating supported Max Frame Size (VxLAN, LISP, |
104 | | <https://jira.fd.io/browse/CSIT-1801>`_ | SRv6). |
105 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
106 | 7 | `CSIT-1802 | AF-XDP - NDR tests failing from time to time. |
107 | | <https://jira.fd.io/browse/CSIT-1802>`_ | |
108 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
109 | 8 | `CSIT-1804 | All testbeds: NDR tests failing from time to time. |
110 | | <https://jira.fd.io/browse/CSIT-1804>`_ | |
111 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
112 | 9 | `CSIT-1808 | All tests with 9000B payload frames not forwarded over memif interfaces. |
113 | | <https://jira.fd.io/browse/CSIT-1808>`_ | |
114 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
115 | 10 | `CSIT-1827 | 3n-icx, 3n-skx: all AVF crypto tests sporadically fail. 1518B with no traffic, IMIX with excessive |
116 | | <https://jira.fd.io/browse/CSIT-1827>`_ | packet loss. |
117 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
118 | 11 | `CSIT-1835 | 3n-icx: vppecho BPS tests failing on timeout when checking hoststack finished. |

120 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
121 | 12 | `CSIT-1849 | 2n-skx, 2n-clx: UDP 16m tput tests fail to create all sessions. |

131 | # | JiraID | Issue Description |
132 +====+=========================================+===========================================================================================================+
133 | 1 | `CSIT-1834 | 2n-icx, 2n-skx: sporadic AVF soak tests failing to find critical load with PLRsearch. |
134 | | <https://jira.fd.io/browse/CSIT-1834>`_ | |
135 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
136 | 2 | `CSIT-1846 | 2n-skx, 2n-clx, 2n-icx: ALL 1518B TCP tput tests failing with big packet loss. |
137 | | <https://jira.fd.io/browse/CSIT-1846>`_ | |
138 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
139 | 3 | `CSIT-1851 | trending regression: various icelake tests around 2202-04-15 |
140 | | <https://jira.fd.io/browse/CSIT-1851>`_ | Somewhat expected consequence of a VPP usability fix, |
141 | | | the previous VPP compiler version was too new for the OS used. |

146 Root Cause Analysis for Performance Changes

149 List of RCAs in |csit-release| for VPP performance changes:
151 +----+-----------------------------------------+-------------------------------------------------------------------------------------+
152 | # | JiraID | Issue Description |
153 +====+=========================================+=====================================================================================+
154 | 1 | `VPP-2030 | regression: ip6base on ICX around 2022-03-23 |
155 | | <https://jira.fd.io/browse/VPP-2030>`_ | "Loads blocked due to overlapping with a preceding store that cannot be forwarded." |
156 | | | started happening in ip6-lookup graph node. |
157 +----+-----------------------------------------+-------------------------------------------------------------------------------------+
158 | 2 | `CSIT-1852 | 2n-zn2 mellanox performance cap |
159 | | <https://jira.fd.io/browse/CSIT-1852>`_ | Old issue, only now distinguished from CSIT-1751. |
160 | | | This testbed+nic combination is capped below 28 Mpps, cause not identified yet. |
161 +----+-----------------------------------------+-------------------------------------------------------------------------------------+
162 | 3 | `CSIT-1853 | trending regression: nat44ed cps around 2202-04-01 |
163 | | <https://jira.fd.io/browse/CSIT-1853>`_ | VPP change added more computation to slow path (in order to support multiple VRFs). |
164 | | | Not clear if the VPP implementation is optimized enough. |
