You know how it is, caching plugins only make the front-end move faster but when you're logged in and browsing the wp-admin section, the Wordpress site grinds to a halt. I'm trying to increase some backend speed of my Wordpress site and would like to know what are the best PHP and server settings to get the speed improved.
Currently my settings are as follows:
- PHP Version: 7.4
- PHP Memory Limit: 512mb (Should I add more?)
- PHP Time Limit: 300 (Should I add more?)
- PHP Max Input Vars: 2500 (What's a good number here?)
- Web Server: Apache with NGINX proxy
Does Redis or Varnish do anything for the backend?
