I’m running Plex via Docker on a Synology NAS. This has been working fine. When I tried to fire up a Jellyfin container, it was painfully slow. Clients barely worked. It wasn’t a good experience. It was several months ago, so I don’t remember all the details.
I run Jellyfin in Docker on an N100 mini PC without problems.
I’ve been running Plex on various devices for many years and have been impressed by the stability and usefulness. Grandfathered on the old lifetime subscription but I get that $750 seems excessive.
I just set up Jellyfin on an 1819 this weekend and so far it seems great, dunno if it’s improved or my device has bit more oomph - the ui on some devices is not as nice as plex but it’s been great
I wonder if it was just a start up issue? Some kind of initial scan of your database?
Could be the hardware acceleration was not mounted to the container.
I don’t know if it’s a synology related problem or just Jellyfin but I have never gotten it running well. Even when it’s running I always get hiccups like server crashed a week later but appears green and running. Or trouble logging into the server using a third party client. Plex has always been perfect for me.
