#. **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.
+ - *MRR tests* - Maximum Receive Rate tests measure the packet forwarding rate

- - *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.
+ - *MLR tests* - NDR and PDR tests measure the packet forwarding rate using
+ MLRsearch library by traffic generator. All tests that previously used
+ binary search were converted to MLRsearch.
+
+ - *L2patch tests* - Tests measure performance of L2patch, cross linking
+ RX and TX of two physical interfaces.
+
+ - *2-node tests* - Baseline set of 2-node tests covering base ip4, ip4,
+ l2patch, l2bd, l2xc.
+
+ - *Generated tests* - Simplified and unified test structure,
+ semi-autogenerated by generator script. Test generator is currently able
+ to create test combinations with various frame size and cores combinations.
+ All existing test cases were converted to new format.
+
+ - *Simultaneous multithreading* - SMT-aware automatic detection and
+ resource configuration including thread affinity, number of rx queues and
+ DPDK I/O mbufs. Tests are automatically tagged during execution indicating
+ configuration.
+
+ - *Intel Skylake* - Topologies consisting of 2-node and 3-node using
+ SuperMirco servers each equipped with two Intel Xeon Skylake Platinum
+ processors.

Performance Changes
-------------------
-Relative performance changes in measured packet throughput in CSIT
-|release| are calculated against the results from CSIT |release-1|
+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
+verify test results repeatability, 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.
