I have put together a set of queries, the output, and corresponding xml.
I have run the first query; it yields no results. Is this expected? If you want, you can send me some more data in private.
Could you please pass me on the query info output for both 8.5.2 and 7.9?
I appreciate your support.

Hi Carl, hi Luiz,
With every version of BaseX, we are adding new query optimizations (usually, this can be experienced if you run newer code with older version of BaseX). Existing optimization should of course be preserved. To be able to understand why your queries run slower than before, I would be more than glad if you could both provide me with little examples that we can try by ourselves. The Query Info output for both versions of BaseX would be helpful as well; it indicates which optimizations are performed or not.
Thanks in advance
Christian

These queries are called from an XSLT transformer via all callout and are performed in very type loops. I was wondering why the transforms were never completing. 40-70x decrease in performance would slow any process down.

I am seeing huge differences in the performance of a multi-threaded JBoss application recently upgraded from 7.9 to 8.4. The problem is that 8.4 is much slower than 7.9. Any ideas? Do I need to add indices or something along those lines?
