I'll share what size it is on mine when I get access to it later today.

Edit:

I just checked the sizes of my DB files.
They are as follows:

library.db = 56MB
library.db-wal = 106MB

Docker stats for my test instances.

Code:
CONTAINER ID   NAME                      CPU %     MEM USAGE / LIMIT     MEM %     NET I/O   BLOCK I/O         PIDS

46849591f45b   jellyfin-stable-testing   0.01%     953.9MiB / 31.09GiB   3.00%     0B / 0B   1.63GB / 1.06GB   21

e1db2e291ed3   jellyfin-unstable         0.01%     640.9MiB / 31.09GiB   2.01%     0B / 0B   3.59GB / 3.41GB   17

My stable testing instance has the same library as my production instance, memory stats for my production instance below (package install in Ubuntu).

Code:
chris@rat-trap:~$ ps -p 3816 -o %cpu,%mem,cmd

%CPU %MEM CMD

 0.4  2.5 /usr/bin/jellyfin

2.5% of 32GB is ~820MB.

My library.db size for 250 movies, 4400 episodes, 4200 songs, 64 audiobooks, and 500 music videos is 107MB.

Code:
chris@rat-trap:~$ ll -h /var/lib/jellyfin/data/library.db

-rw-r--r-- 1 jellyfin jellyfin 107M Jun 12 10:12 /var/lib/jellyfin/data/library.db

And the metadata directory is 14GB.

Code:
chris@rat-trap:~$ du -sh /var/lib/jellyfin/metadata/

14G     /var/lib/jellyfin/metadata/

So this is where the problem lies! My library.db is 3.5GB, and my Jellyfin container, without any memory limit, is now occupying 15GB. If your library.db is as large as mine, I guess you would also encounter the same awkward situation as me, having to wait a long time for it to finish starting up!

Under Scheduled Tasks there's a task called Optimise database. When has this run last time?

13 hours ago, in fact, the database optimization feature you mentioned runs once a day on my device. However, it doesn’t seem to help much. The database is indeed that large, I estimate it contains no less than 40,000 movies…
