Bug 60098

Summary: Report / Dashboard : Reduce default value for "jmeter.reportgenerator.statistic_window" to reduce memory impact

Description Philippe Mouawad 2016-09-08 19:38:20 UTC
With the introduction of new report ResponseTimePercentilesOverTime the number of instances using DescriptiveStatistics will grow and have important memory footprint.

For example, generation of a big load test lasting 2 hours, uses more than 1go of Heap.

Today jmeter.reportgenerator.statistic_window=200000
To reduce this impact we can decrease the window to 10000.

Another possibility is to add a notification method when switching time period to next one.
This would allow the extraction of percentile and nullification of DescriptiveStatistics instance.
