1GB is egregious for what amounts to a file server that can spawn ffmpeg. Plex uses like 10x less. Last time I tried Jellyfin it ate 9GB and nuked my NAS out of existence, purely because it tried to scan my fairly modest library.
C# on .NET is pretty horrible on resources and efficiency for stuff like this - this also sometimes happens to a lot of the more established *arr software
Here’s Plex currently generating some audio loudness data on an entire season in the background. In a container (it’d be even leaner if it ran bare metal). I’ve never seen it even reach 500MB under the worst circumstances imaginable.
