> Ever since multithreaded search (SOLR-13350) was introduced, there has been not much effort to benchmark the performance benefit or investigate the performance bottlenecks. Anecdotally, it is not faster than single threaded execution.
> Thanks to [~kevinliang01] [~liangkaiwen] [~liangkw16] and [~dsmiley] for bringing this up, yesterday on a dense vector working group meeting.
> I'm marking this as a release 10.0 blocker, because it is embarrassing to be releasing with such a gaping hole.
