I profiled the db:open() and collection() calls and they were basically instantaneous.
Moving to using db:attribute() and the index makes my process 100x times faster. Now I feel like a bit of an idiot for not having figured this out sooner.
Nah, optimization is tricksy. Glad it's working!
Somebody needs to write the Optimizing BaseX book….

can you take the db:open() call out and see how much faster the expression runs without it?
return (db:option('attrindex'), let $db := db:open($rkDatabase) return for $node in $map
return prof:track($db/doc-where-used-index/where-used-entry /@key[xs:integer(.) eq 9151416])?time ! util:formatTime(.)
(if i have that right)
