From 4dcba2ee61b44a1dbcb295ad05f3a6d913da354f Mon Sep 17 00:00:00 2001 From: Tomas Cohen Arazi Date: Wed, 15 Sep 2021 12:12:33 -0300 Subject: [PATCH] Bug 29032: Pre-load ILL backends to speed up response Bug 22440 will rewrite the route and make it even more efficient by prefetching the related data instead of performing several queries in loops. In the meantime, we can make this controller perform better with a simple intervention: load backends once, and use the $request->_backend() setter to pre-set it before using the objects. To test: 1. Perform any usual ILL requests listing, try having several => FAIL: Notice it takes a weird amount of time to load 2. Apply this patch 3. Restart all 4. Repeat 1 => SUCCESS: It feels fast enough! 5.
