jpountz opened a new pull request, #13606:
URL: https://github.com/apache/lucene/pull/13606
This iterates on #13546 to further reduce the overhead of search concurrency
by caching whether the hit count threshold has been reached: once the threshold
has been reached, it cannot get "un-reached" again, so we don't need to pay the
cost of `LongAdder#get`.
