Very long scanning time for music - tom707 - 2025-08-15
Hey there,
I decided to use Jellyfin for music I bought. I already use it for movies and books.
Until I added my music, the manual (meaning clicking the button) libraries scans were quite fast - like it just took minutes if I added a new series, for instance.
Since I added my music, it takes many hours and is kind of stuck at 95%+. If I start a scan on one day, it's done the next day.
I started with just 30 songs or so, and this already took so long. At the moment, I have ~1500 songs, which have all been scanned once. However, the scan still takes like forever.
Also, the identification and loading of data for new songs takes forever too. I judge the end of a scan by looking at the progress bar in the GUI of my web player.
My research really didn't help: Like disabling LUFS scan didn't help, and I really would like to keep that.
I expect: Since I think gigabytes of videos should be harder to handle than music, I would expect the scan of music to be faster than the scan of my bigger movie library.
I like to buy a song every now and then so it would be nice to have shorter scans.
More details:
I use Jellyfin 10.10.7 (Server, Web, and Build version). Everything is installed via Docker on an Ubuntu Server.
I get metadata via MusicBrainz
