[jira] [Commented] (JCR-2959) SQL2 QueryEngine should use Lucene for sort

    [ https://issues.apache.org/jira/browse/JCR-2959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14744926#comment-14744926 ] 

Ben Frisoni commented on JCR-2959:
----------------------------------

I currently have in the works a patch for both this jira (JCR-2959) and JCR-2830. I was wondering if there is a specific location where query performance tests are being housed?

> Currently all SQL2 queries with "order by" expression are sorted with Collections.sort - which is slow and very bad if there are lots of hits. Lucene should be used for sorting hits instead.
