Performance Changes ------------------- -Substantial changes in measured packet throughput have been observed in a -number of CSIT |release| tests listed below. Relative changes for this release -are calculated against the test results listed in CSIT |release-1| report. The -comparison is calculated between the mean values based on collected and -archived test results' samples for involved VPP releases. Standard deviation -has been also listed for CSIT |release|. +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. -NDR Throughput Changes -~~~~~~~~~~~~~~~~~~~~~~ +NDR Changes +~~~~~~~~~~~ -NDR small packet throughput changes between releases are available in a CSV and -pretty ASCII formats: +NDR small packet throughput changes between releases are available in a +CSV and pretty ASCII formats: - `csv format for 1t1c <../_static/vpp/performance-changes-ndr-1t1c-full.csv>`_, - `csv format for 2t2c <../_static/vpp/performance-changes-ndr-2t2c-full.csv>`_, - `pretty ASCII format for 1t1c <../_static/vpp/performance-changes-ndr-1t1c-full.txt>`_, - `pretty ASCII format for 2t2c <../_static/vpp/performance-changes-ndr-2t2c-full.txt>`_. -PDR Throughput Changes -~~~~~~~~~~~~~~~~~~~~~~ +PDR Changes +~~~~~~~~~~~ -NDR small packet throughput changes between releases are available in a CSV and -pretty ASCII formats: +NDR small packet throughput changes between releases are available in a +CSV and pretty ASCII formats: - `csv format for 1t1c <../_static/vpp/performance-changes-pdr-1t1c-full.csv>`_, - `csv format for 2t2c <../_static/vpp/performance-changes-pdr-2t2c-full.csv>`_, - `pretty ASCII format for 1t1c <../_static/vpp/performance-changes-pdr-1t1c-full.txt>`_, - `pretty ASCII format for 2t2c <../_static/vpp/performance-changes-pdr-2t2c-full.txt>`_. -Measured improvements are in line with VPP code optimizations listed in -`VPP-18.01 release notes -`_. +MRR Changes +~~~~~~~~~~~ + +MRR small packet throughput changes between releases are available in a +CSV and pretty ASCII formats: + + - `csv format for 1t1c <../_static/vpp/performance-changes-mrr-1t1c-full.csv>`_, + - `csv format for 2t2c <../_static/vpp/performance-changes-mrr-2t2c-full.csv>`_, + - `csv format for 4t4c <../_static/vpp/performance-changes-mrr-4t4c-full.csv>`_, + - `pretty ASCII format for 1t1c <../_static/vpp/performance-changes-mrr-1t1c-full.txt>`_, + - `pretty ASCII format for 2t2c <../_static/vpp/performance-changes-mrr-2t2c-full.txt>`_, + - `pretty ASCII format for 4t4c <../_static/vpp/performance-changes-mrr-4t4c-full.txt>`_. + +Throughput Trending +------------------- + +In addition to reporting throughput changes between VPP releases, CSIT +provides continuous performance trending for VPP master branch: + +#. `VPP Performance Dashboard `_ + - per VPP test case throughput trend, trend compliance and summary of + detected anomalies. + +#. `Trending Methodology `_ + - throughput test metrics, trend calculations and anomaly + classification (progression, regression, outlier). + +#. `Trendline Graphs `_ + - per VPP build MRR throughput measurements against the trendline + with anomaly highlights, with associated CSIT test jobs.
