See bug 24185, this avoids looping every each item of the record for every item of the record
How to reproduce:
1) on freshly installed kohadevbox create/import one book,
remember that biblionumber for later use it in down below,
2) add 100 items for that book for some library,
3) find some patron, that patron's card number we will
use as a borrower down below to open holds page,
4) check for the rule or set up a single circulation rule
in admin "/cgi-bin/koha/admin/smart-rules.pl",
that rule should match above book items/library/patron,
check that rule to have a non-zero number of holds (total, daily, count) allowed,
and, IMPORTANT: set up "On shelf holds allowed" to "If all unavailable",
("item level holds" doesn't matter).
5) open "Home > Catalog > THAT_BOOK > Place a hold on THAT_BOOK" page
("holds" tab), and enter patron code in the search field,
or you can create a direct link by yourself, for example, in my case it was:
/cgi-bin/koha/reserve/request.pl?biblionumber=4&findborrower=23529000686353
6) it should be pretty long page generation time on old code, densely increasing for every hundred items added. In the case of this solution, it's fast, and time increases a little only, linear.
In testing with 100 books I went from ~6.5 seconds to ~3.2 seconds
