> 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 ?
