[basex-talk] Performance problem with function declaration

Hi Using Basex 7.0.2 and the factbook.xml database, I observe the following: declare variable $data:=db:open("factbook");

declare function local:myid1($id){ $data//*[@id=$id] }; (: get a 1000 ids to test :) let $ids:=subsequence($data//@province/string(.),1,1000)

for $s in $ids return local:myid1($s)

Takes 30 seconds! Replacing the final line with

for $s in $ids return $data//*[@id=$s]

The time is 123ms. /Andy
