My Gitea base on docker access is very slow, please help

I install and deploy the Gitea on my docker server.
After install and deploy, I access the URL.
The first page is very quick to access, but when try to registry or login and using the functions in Gitea, the web pages load are very slow. Seems each time will cost 60s.
Can anyone help for this issue? Thanks a lot

Check the local mode resolve the issue. Thanks
