We've been testing Moodle with PHP 7.4 for a while now. We upgraded from PHP 7.4.11 to 7.4.15 recently, and Moodle started behaving really slow. DB connections and upgrades took longer than before, and SCSS compilation never finished, so we had to roll back to PHP 7.4.11.
We weren't sure of the version actually fixing it until we rolled back. Is there any change in PHP that anyone thinks could impact Moodle badly?
Or are there ini flags we should take into account when using Moodle with PHP 7.4?
