I believe you mean a jellyfin server (as opposed to some jellyfin client), right? Does it serve you as good as it should? Of course transcoding is off-limits, but does 1080p streaming run smoothly on the client(s), even with high bitrates?
That's correct yes. The server runs fine I average a load of less than 1 during a stream. However I do have to use the Applications as using the web interface for the larger files really chugs along.
