Admin of recently migrated site performance is VERY slow. I have recently migrated a site to WPMUDEV host and I am working to finalize settings so that I may update dns. However, my admin interface is incredibly slow, and I don’t know why. (like it took about 2-3 minutes for an update to post to my homepage SEO Crawler settings)
I was using WP Rocket for caching, but that plugin is disabled. The only updates I made to the site after it was migrated was to disable several plugins that aren’t needed anymore due to wpmudev having that functionality.
