> I think #2 is the correct way.
> Maybe we can modify the save_jmh_result.py to correctly set the 'units' and
> the 'lessisbetter' fields of benchmark results. The 'units' is already
> contained in the jmh result and the 'lessisbetter' can be derived from the
> mode(false if it is 'thrpt' mode, otherwise true). An example of the jmh
> result format can be found at https://i.stack.imgur.com/vB3fV.png.
> This can fix the web UI as well as the REST result, and then the
> regression_report.py will be able to identify which benchmarks are "less is
> better" and treat them differently.
