Jukka Zitting updated JCR-2715:
-------------------------------
Attachment: SQL2SearchTest.png
Yes, also non-join SQL2 query performance is now significantly better. The
attached SQL2SearchTest graph shows the performance of a simple non-join SQL2
query that selects 100 nodes out of a set of 10k nodes using a simple property
constraint. The performance improvement is pretty impressive, from 9740ms to
189ms per 100 queries.
