Bug 24185 made a nice fix for the satff client - we should port this to OPAC too
Created attachment 128455 [details] [review] Bug 29685: Reduce item processing by calculating 'items any available' outside of loop 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

We should have actually cached in L1 instead of passing the result around. That would have fix all the different occurrences (luckily there are only 2 of them).
