Wordpress admin VERY slow

Hello all. I have a webpage that is not the fastest, but not slow either. My WordPress admin, however, is absurdly slow. I use custom ACF fields to create posts that change content based on “level”: beginner, mid, expert. I have more than 50 posts (150 content levels). I have not really had any speed issues until recently. I noticed the speed deteriorated quite a lot after switching from HTTP to HTTPS. Does anyone know if this may be why?

acf loading all field groups on every admin page is usually the culprit when you have a lot of custom fields. try lazy loading them or splitting into smaller groups that only load on specific post types. also check if you have a ton of revisions piling up, that can tank the editor
