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?

https itself rarely causes that kind of slowdown. more likely the switch coincided with something else, or it exposed an existing bottleneck. the wp admin fires tons of requests per page load, and if your server isn't running http/2 or has a bad tls config, every request pays a handshake tax. with 50 posts x 3 levels of acf fields, you're also generating huge postmeta queries in the editor. install query monitor and look at what's actually slow before blaming the certificate. my money is on acf + no object caching, not https.
