Przemo Pakulski commented on OAK-2056:
--------------------------------------
As the fix is pretty save and tested already, I would like to have it ported to 1.0.x branch and included in 1.0.12.

> Sorting by date fields is very slow in oak, especially if result set size is large.
> I'm running the following JCR-SQL2 query
> {code}
> SELECT * FROM [cq:PageContent] AS [c] WHERE ISDESCENDANTNODE('/content')
> {code}
> which returns 3270 results on my oak repo.
> {noformat}
> Query execution times are as below
> ---------------------------------------
> No order clause | 0,147 sec
> ORDER BY [jcr:title] | 1,203 sec
> ORDER BY [jcr:createdBy] | 1,018 sec
> ORDER BY [jcr:created] | 25,229 sec
> {noformat}
> Ordering by date field adds extra 24 seconds overhead.
