Slow library scans fix?

To be able to help you, we need to know more about your hardware, jellyfin installation type, OS etc.

If using Linux, have you checked that the permissions of the media libraries are correct set? And or created a jellyfin user so, it has right read/write permissions?

Hello, 
I am using docker compose (yml) on an i7 computer, 16Ram, and HDD external media with linux. I created a jellyfin user.
I checked and reset linux permissions after the last server update. I think they are OK but the permissions is very confusing on linux to me.

I am running this in BASH (usr is my actual usrname).

sudo chown -r usr:usr /mnt/mediadrive
sudo chmod -r 755 /mnt/mediadrive
sudo setfacl -R -m u:jellyfin:rwx /mnt/mediadrive
