-------------------------------------------
Summary: Investigate multithreaded search performance bottlenecks
Key: SOLR-17841
URL: https://issues.apache.org/jira/browse/SOLR-17841
Project: Solr
Issue Type: Improvement
Affects Versions: main (10.0)
Reporter: Ishan Chattopadhyaya
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.
