5 Changes in |csit-release|
6 -------------------------
8 #. VPP PERFORMANCE TESTS
10 - **Service density 2n-skx tests**: Network Function Virtualization (NFV)
11 service density tests focus on measuring total per server throughput at
12 varied NFV service *packing* densities with vswitch providing host
13 dataplane. The goal is to compare and contrast performance of a shared
14 vswitch for different network topologies and virtualization technologies,
15 and their impact on vswitch performance and efficiency in a range of NFV
16 service configurations.
18 - **Experimental Soak Tests**: Added performamce soak tests framework
19 code for extended time duration tests and throughput discovery
20 at given PLR and at give total test time e.g. minutes, hours,
21 days, weeks, months, years. See updated
22 :ref:`test_methodology` section for more details.
26 - **Container code optimizations**: Optimized container library allows to
27 run containre_memif tests faster.
29 - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to
30 PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away
33 - **General Code Housekeeping**: Ongoing RF keywords optimizations,
34 removal of redundant RF keywords.
36 #. PRESENTATION AND ANALYTICS LAYER
38 - **Graphs Layout Improvements**: Improved performance graphs layout
39 for better readibility and maintenance: test grouping, axis
40 labels, descriptions, other informative decoration.
44 - **3n-dnv Tests (3rd Party)**: Published performance tests for 3n-
45 dnv (3-Node Atom Denverton) from 3rd party testbeds running FD.io
46 |csit-release| automated testing code.
47 Only graphs for Packet Throughput and Speedup Multi-core and not
48 for Packet Latency were published as there are no results for Packet
53 |csit-release| report was generated with a single run of selected
54 64B frame performance tests on 3n-hsw and 3n-skx test beds
55 in order to spot-check the main data plane paths.
56 NFV service density and soak tests were not run and do not feature in
