Relative improvements 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|. VPP-16.09 and VPP-17.01 numbers are -provided for reference. +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 -~~~~~~~~~~~~~~ +NDR Throughput Changes +~~~~~~~~~~~~~~~~~~~~~~ -Non-Drop Rate Throughput discovery tests: +NDR small packet throughput changes between releases are available in a CSV and +pretty ASCII formats: -.. csv-table:: - :align: center - :file: performance_improvements/performance_improvements_ndr_top.csv + - `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 -~~~~~~~~~~~~~~ +PDR Throughput Changes +~~~~~~~~~~~~~~~~~~~~~~ -Partial Drop Rate thoughput discovery tests with packet Loss Tolerance of 0.5%: +NDR small packet throughput changes between releases are available in a CSV and +pretty ASCII formats: -.. csv-table:: - :align: center - :file: performance_improvements/performance_improvements_pdr_top.csv + - `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>`_.
