Review Comment:
I thought about using SortTuningRecordByMeanRunSecs, but memory_database is
not sorted unlike json_database.
This constant appears in all tuners and unfortunately there is no common
definition for it.
I can suggest to make an NFC patch with refactoring this constant throughout
the repository.
