4 Changes in |csit-release|
5 -------------------------
7 #. **VPP Performance Tests**
9 - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
10 configurable trial duration and number of consecutive executions.
11 Coverage of MRR tests has been extended across more test
12 scenarios. MRR tests are used for continuous performance trending
13 and for comparison between VPP releases.
15 - **MLRsearch Throughput**: MLRsearch algorithm has been introduced
16 for all NDR and PDR throughput tests. All tests that previously
17 used binary search got converted to MLRsearch. Coverage of NDR/PDR
18 tests has been extended across more test scenarios.
20 - **L2patch Tests**: Tests measure performance of VPP L2patch, the
21 fastest L2 forwarding path implemented in VPP, that cross-links
22 RX and TX of two physical interfaces.
24 - **2-Node Tests**: A new baseline set of 2-node tests covering base
25 ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake
28 - **Generated tests**: Simplified and unified test structure, semi-
29 autogenerated by generator script. Test generator is currently
30 able to create test combinations with various frame size and
31 cores combinations. All existing test cases were converted to new
34 - **Simultaneous Multi-Threading**: SMT-aware detection of server
35 processor operation mode (HyperThreading enabled/disabled) with
36 associated compute resource configuration including thread
37 affinity, number of Rx queues and DPDK I/O mbufs. Tests are
38 automatically tagged during execution to indicate executed thread
41 - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node
42 physical testbed topologies based on the new SuperMirco servers
43 each with two Intel Xeon Skylake Platinum processors. Full
44 Ansible playbooks refactor for quick server (re)installation and
45 reference pointers of configuration.
47 #. **Presentation and Analytics Layer**
49 - **Performance trending**: Further improved continuous performance
50 trending with anomaly detection and analysis.
52 #. **Test Framework Optimizations**
54 - **General Code Housekeeping**: Ongoing RF keywords optimizations,
55 removal of redundant RF keywords.
60 Relative performance changes in measured NDR, PDR and MRR packet
61 throughput in |csit-release| are calculated against the test results
62 from |csit-release-1| report, for tests running on 3-Node Intel Xeon
63 Haswell testbeds (3n-hsw) in 1-core, 2-core and 4-core (MRR only)
66 Listed mean and standard deviation values are computed based on a series
67 of the same tests executed against respective VPP releases to verify
68 test results repeatability, with percentage change calculated for mean
69 values. Note that the standard deviation is quite high for a small
70 number of packet throughput tests, what indicates poor test results
71 repeatability and makes the relative change of mean throughput value not
72 fully representative for these tests. The root causes behind poor
73 results repeatability vary between the test cases.

199 In addition to reporting throughput changes between VPP releases, CSIT
200 provides continuous performance trending for VPP master branch:
202 #. `VPP Performance Dashboard <https://docs.fd.io/csit/master/trending/introduction/index.html>`_
203 - per VPP test case throughput trend, trend compliance and summary of
206 #. `Trending Methodology <https://docs.fd.io/csit/master/trending/methodology/index.html>`_
207 - throughput test metrics, trend calculations and anomaly
208 classification (progression, regression, outlier).
210 #. `Trendline Graphs <https://docs.fd.io/csit/master/trending/trending/index.html>`_
211 - per VPP build MRR throughput measurements against the trendline
212 with anomaly highlights, with associated CSIT test jobs.
