I have setup so many instances over the months on different servers and the web ui always takes 40s to a minute to load per page I have always used redis for caching and the best methods even the aio docker image(s) are really slow.
kind of just been living with it for the past month or so but its really annoying when others are saying theirs takes seconds to load.
edit: totally didn’t forget to include a body
If you only want online file storage and sync, you may want to try Seafile. It’s a lot faster and has been rock solid since 10+ years for me. Not viable if you need some of the many nextcloud exentions though
