After registration, the refresh of files and control panel becomes slow? Will registration affect the response speed of the system? The contrast is very obvious.Why?
No, the registration can't affect anything really.
It is something else that is causing this for you. Try disabling Gravatar support from the control panel, under third-party services.
Thank you very much! That's why I checked the server environment for 2 days.
The problem has been solved, and it's very fast now！
It's a great piece of software！
