Hello, A user recently reported a bug on StatCalculator class: - https://bz.apache.org/bugzilla/show_bug.cgi?id=61071
It appears issue is not restrained to Median but concerns percentile computing. Besides, this class has many drawbacks: - It is not tested as much as it should be - It relies on an algorithm that consumes memory We use another class in Web/Dashboard report and BackendListener client implementations that relies on commons-math org.apache.commons.math3.stat.descriptive.DescriptiveStatistics. My proposal is the following: - First step : Introduce in StatCalculator, HdrHistogram - Second step : Replace DescriptiveStatistics by HdrHistogram Benefits: - Uniform computing accross JMeter - Better performances Are you ok with this approach ? Thanks -- Regards. Philippe Mouawad. Ubik-Ingénierie
