   @jbellis would this change effect query per second? There is a 20% drop since this commit in QPS in Lucene bench nightlies:
   
   https://home.apache.org/~mikemccand/lucenebench/2023.05.08.18.03.38.html
   
   Looking at the other searches, none slow down this significantly, so it doesn't seem to be the lucene util change.
   
   Did your testing for recall changes show any performance differences on single threaded QPS?
