Hi @thatryan
Does this slowness build up while navigating the front of the site?
If it’s only the backend, it is likely a plugin that is attempting to do something that is slowing the site down.
You might also try installing the Query Monitor plugin https://wordpress.org/plugins/query-monitor/
which can give you insight as to what things WordPress and the underlying plugins are doing that are eating up the computer’s resources.
Let me know what you find out!
