Since the manual update I performed on my site I've been having ultra slow response times on my WP-Admin Site.
I've tried disabling plugins and Themes by no effect. I notice it is very slow only when I am in Admin or in Admin preview of the site and the Dashboard/plugins/themes sections are particularly slow to load (but overall is very very slow)
I have direct access to the server which I am running on my own, so no server provider here.
Can permissions database/files hinder the performance of the admin? Since I had to re-upload some files from a backup after a failed update, I had to reset permissions on the files, but I am not sure it caused the problem.
Maybe some tips to diagnose and solve the problem?
