[Exist-open] Instrumenting XQL for millisecond time

[Len S. <le...@wi...>]

I’m trying to instrument my XQL so I can see how long functions take to execute.

I tried current-dateTime(), but that returns the same millisecond timestamp at all points of the code, apparently being the time the XQL started.  Is there a way to do this?  Marklogic seems to have xdmp:elapsed-time(), but I don’t see something similar in eXist.  But even that may not work for XQL being an OOO functional language.

What’s the best way to profile the latency of functions?
