6 Changes in |csit-release|
7 -------------------------
9 #. VPP PERFORMANCE TESTS
11 - **Intel Xeon Ice Lake**: Added test data for these platforms. Current
12 CSIT-2110 report data for Intel Xeon Ice Lake comes from an external source
13 (Intel labs running CSIT code on "8360Y D Stepping" and "6338N"
14 processors). For details about the physical setup see
15 :ref:`tested_physical_topologies`.
17 - **MLRsearch improvements**: Added support for multiple packet
18 throughput rates in a single search, each rate is associated
19 with a distinct Packet Loss Ratio (PLR) criterion. Previously
20 only Non Drop Rate (NDR) (PLR=0) and single Partial Drop Rate
21 (PDR) (PLR<0.5%) were supported. Implemented number of
22 optimizations improving rate discovery efficiency.
24 - **Reduction of tests**: Removed obsolete VPP use cases and
25 superfluous test combinations from continuous and report test
26 executions, including:
28 - All vts tests, obsolete use cases.
29 - dot1q tests apart from dot1q-l2bd, superfluous combinations.
30 - -100flows, -100kflows in all acl tests.
33 - -pps tests, replaced by -tput tests.
34 - h1-p1-s1 single session tests, unessential combination.
35 - h4096-p63-s258048 tests, unessential scale combination.
39 - ethip4ipsectptlispgpe.
41 - policy-aes128cbc-hmac256sha.
42 - policy-aes128cbc-hmac512sha.
43 - int-aes128cbc-hmac256sha.
53 - **CSIT test environment** version has been updated to ver. 8, see
54 :ref:`test_environment_versioning`.
56 - **CSIT in AWS environment**: Added CSIT support for AWS c5n
57 instances environment.
59 - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
60 still used in CSIT for all VPP scale tests. See known issues
63 - **General Code Housekeeping**: Ongoing code optimizations and bug
66 #. PRESENTATION AND ANALYTICS LAYER
68 - **Graphs improvements**: Updated Packet Latency graphs,
69 see :ref:`latency_methodology`.
80 List of known issues in |csit-release| for VPP performance tests:
82 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
83 | # | JiraID | Issue Description |
84 +====+=========================================+===========================================================================================================+
85 | 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. The issue persists after FVL FW upgrade. |
86 | | <https://jira.fd.io/browse/CSIT-1782>`_ | |
87 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
88 | 2 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
89 | | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
90 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
91 | 3 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
92 | | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
93 | +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
94 | | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
95 | | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
96 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
97 | 4 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
98 | | <https://jira.fd.io/browse/CSIT-1789>`_ | This increases standard deviation of tests with small number of flows (mainly ipsec). |
99 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
100 | 5 | `CSIT-1780 | IPSEC SW async scheduler MRR tests failing with no traffic forwarded. |
101 | | <https://jira.fd.io/browse/CSIT-1780>`_ | |
102 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
103 | 6 | `CSIT-1786 | IP4 and IP6 scale tests failing with no traffic forwarded. |
104 | | <https://jira.fd.io/browse/CSIT-1786>`_ | Issue reported to VPP devs. |
105 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
106 | 7 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
107 | | <https://jira.fd.io/browse/CSIT-1785>`_ | |
108 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
109 | 8 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
110 | | <https://jira.fd.io/browse/CSIT-1791>`_ | |
