Speed up Wordpress backend

Hey team awesome!
When i'm not able to figure out things you guys are my very best friends!

I'm running a Siteground GoGeek solution
Kleo theme
Buddypress
OptimizePress (4 plugins total)
- And then some basic plugins
Heartbeat control should help, but i can't feel the different.
.
.
My backend is very slow (Screenrecord here).
Iv'e other sites with +10 more plugins installed so i can't believe this is the problem? Kleo theme is very low on requests based on test from pingdom. Do you have any fix, idea to solve this? I can provide you all you need, cpanel, ftp etc. (if you're lucky a lapdance from my friend too)
.
.
If you want me to write Kleo or OptimizePress let me know - and what to write.

I've already grented you access to the site Emographics.dk

Remember to turn on developer mode for Cloudflare (See screenshot)

Can't wait to hear from you
