Marios Trivyzas commented on LUCENE-10423:
------------------------------------------

Should [https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/time/StopWatch.html] be used to measure elapsed time?

> Followup to LUCENE-10421
> Code in the library shouldn't rely on wall-clock time. If you look at all the places doing this, they are basically all bad news.
> Most tests doing this are "iterating for some amount of wall-clock time" which causes them to instead just be non-reproducible. These should be changed to use a fixed number of loop iterations instead.
> It would really be great to ban this stuff in forbidden apis. It is even in the configuration file, just currently commented out.
