Bug ID: 60098
Summary: Report / Dashboard : Reduce default value for
"jmeter.reportgenerator.statistic_window" to reduce
memory impact
Product: JMeter
Version: 3.0
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P2
Component: Main
Assignee: [email protected]
Reporter: [email protected]
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.
