Changes in |csit-release|
-------------------------
-#. **VPP performance tests**
+#. VPP PERFORMANCE TESTS
- - *MRR tests* - New Maximum Receive Rate tests measure the packet
- forwarding rate under the maximum load offered by traffic
- generator over a set trial duration, regardless of packet loss.
- MRR tests are used for continuous performance trending and for
- comparison between releases.
+ - **Service density 2n-skx tests**: Added higher NF density tests with two
+ NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now
+ used as a VNF payload similar to CNF tests.
- - *Service Chaining with SRv6* - New SRv6 (Segment Routing IPv6) proxy
- tests measure performance of SRv6 Endpoint fronting SR-unaware
- appliance via masquerading (End.AM), dynamic proxy (End.AD) or
- static proxy (End.AS) SR functions.
+ - **Soak Tests**: Optimized performamce soak tests framework
+ code for extended time duration tests and throughput discovery
+ at given PLR and at give total test time e.g. minutes, hours,
+ days, weeks. See updated
+ :ref:`test_methodology` section for more details.
-#. **Presentation and Analytics Layer**
+#. TEST FRAMEWORK
- - *Performance trending* - Added continuous performance trending and
- analysis. New Performance Trending and Performance Analysis jobs
- executed regular throughput tests, with results being subsequently
- analysed and trend and anomalies summarized and presented in VPP
- Performance Dashboard and trendline graphs.
+ - **Qemu code refactor**: Complete code refactor of the key components of
+ QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added
+ implementation of kernel-image-kvm based VM replacing the previously used
+ NestedVM images. Added ability to run VPP as a payload in VNF.
-#. **Test Framework Optimizations**
+ - **CSIT PAPI Support**: Continued conversion of CSIT VAT L1 keywords to
+ PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components
+ of PAPI Executor and PAPI history.
- - *Performance tests efficiency* - Qemu build/install optimizations,
- warmup phase handling, vpp restart handling. Resulted in improved
- stability and reduced total execution time by 30% for single pkt
- size e.g. 64B/78B.
-
- - *General code housekeeping* - ongoing RF keywords optimizations,
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
removal of redundant RF keywords.
-Performance Changes
--------------------
-
-Relative performance changes in measured packet throughput in CSIT
-|release| are calculated against the results from CSIT |release-1|
-report. Listed mean and standard deviation values are computed based on
-a series of the same tests executed against respective VPP releases to
-verify test results repeatibility, with percentage change calculated for
-mean values. Note that the standard deviation is quite high for a small
-number of packet throughput tests, what indicates poor test results
-repeatability and makes the relative change of mean throughput value not
-fully representative for these tests. The root causes behind poor
-results repeatibility vary between the test cases.

-Throughput Trending
--------------------

+ #. MISCELLANEOUS
-In addition to reporting throughput changes between VPP releases, CSIT
-provides continuous performance trending for VPP master branch:
+ - **2n-dnv Tests (3rd Party)**: Published performance tests for 2n-
+ dnv (2-Node Atom Denverton) from 3rd party testbeds running FD.io
+ |csit-release| automated testing code.
+ Only graphs for Packet Throughput and Speedup Multi-core and not
+ for Packet Latency were published as there are no results for Packet
+ Latency available.
