We've had a search performance regression on 2025-05-01. https://benchmarks.mikemccandless.com/FilteredIntNRQ.html https://benchmarks.mikemccandless.com/2025.05.01.10.59.59.html I'm not sure which change is responsible for this yet, the two changes that caught my eye in the diff are Remove abstractions of MMapDirectory <https://github.com/apache/lucene/pull/14564> and Create file open hints on IOContext to replace ReadAdvice <https://github.com/apache/lucene/pull/14482>. I will do a git bisect in the next few days if nobody beats me to it. -- Adrien
