I have a QNAP TS-253D (Celeron J4125, 4GB RAM) hosting all my files. I used to have Jellyfin running on it in a Docker container, but it performed really poorly (which is expected ig). It used to take forever to stream a 1080p movie, and seeking back and forth would freeze the whole thing.

Then I moved my Jellyfin setup to my desktop PC (i9-10850k, 16GB RAM, 2080 Super), the files are still on my NAS. It performs much better now, streaming is a breeze and it almost never freezes or anything.

Problem is, it eats up all my RAM. My RAM usage is 99% almost all the time someone uses Jellyfin and it significantly hampers my regular work on my desktop. I can upgrade my RAM to 32 or 64 GB, but would that solve the problem?

If not, what is the cheapest mini PC or home setup that I can do that’d free up my desktop but still give me similar or at least good enough performance?

Thank you for your advice.

    Running Jellyfin on my old Pentium E5200 (dual core), 4 GiB memory. I use FreeBSD with ZFS, but I use AppJail to manage my FreeBSD containers (>15). It works very well. There is no performance difference between containers and host (at least on FreeBSD): Jellyfin consumes up to 400-500 MiB of memory with a single client, a bit more when some other client wants to play a movie, but in general I use movian on my PS3 or the Jellyfin app on my android device. When I rewind or fast forward the movie it only hangs 1 or 2 seconds depending on network traffic (in general the rate is low) but I think the Jellyfin app or Movian prefetch chunks of the movie and caches it to improve performance a bit. I think the other thing that helps me not to consume a lot of my resources is that my movies are usually of decent quality, but not the best, as they are either classics or too recent to be of decent quality.

    I don’t test the following because I don’t need to, but maybe it can be useful to you:
