Ishan Chattopadhyaya commented on SOLR-13350:
---------------------------------------------
Latest patch here:
https://github.com/apache/solr/compare/apache:main...apache:jira/solr-13350
(I can't create a PR, since Github can't identify me as a collaborator).
Status:
* Search is faster
* Faceting is slower
Investigating the slowdown in faceting when using multiple threads. Just a
note: When I replace the ThreadSafeBitSet (originally borrowed from Netflix's
zeno project) with a non-threadsafe version, speed is better but results are
wrong.

> AFAICT, SolrIndexSearcher can be used only to search all the segments of an
> index in series. However, using CollectorManagers, segments can be searched
> concurrently and result in reduced latency. Opening this issue to explore the
> effectiveness of using CollectorManagers in SolrIndexSearcher from latency
> and throughput perspective.
