> Currently, regressions are detected by a simple script which may have false
> positives and false negatives, especially for benchmarks with small absolute
> values, small value changes would cause large percentage changes. see
> [here|https://github.com/apache/flink-benchmarks/blob/master/regression_report.py#L132-L136]
> for details.
> And all benchmarks are executed on one physical machine, it might happen that
> hardware issues affect performance, like "[FLINK-18614] Performance
> regression 2020.07.13".

> script.
