Linked trendline graphs enable further drill-down into the +trendline compliance, sequence and nature of anomalies, as well as +pointers to performance test builds/logs and VPP (or DPDK) builds. +Performance trending is currently based on the Maximum Receive Rate (MRR) tests. +MRR tests measure the packet forwarding rate under the maximum load offered +by traffic generator over a set trial duration, regardless of packet +loss. See :ref:`trending_methodology` section for more detail including +trend and anomaly calculations. + +Data samples are generated by the CSIT VPP (and DPDK) performance trending jobs +executed twice a day (target start: every 12 hrs, 02:00, 14:00 UTC). All +trend and anomaly evaluation is based on an algorithm which divides test runs +into groups according to minimum description length principle. +The trend value is the population average of the results within a group. + +Tested VPP worker-thread-core combinations (1t1c, 2t1c, 2t2c, 4t2c, 4t4c, 8t4c) +are listed in separate tables in section 1.x. Followed by trending methodology +in section 2. and trending graphs in sections 3.x. Performance test data +used for trending graphs is provided in sections 4.x. |
