This is me too. I’ve got about 5TB of material being seeded 24/7 from my media seever, but I rarely see more than single-digit GB total upload volume per day. The majority of the time, except for the occasional blip, I rarely see total upload rate get over a few hundred kB/s despite having the cap at 24MB/s.
I’d have to stop torrenting completely and only seed for a year to get my ratio past 2.0 lol
I don’t have specific troubleshooting advice to give, but I have been using an Nvidia Shield Pro as my main streaming device for about 4 years now. It is overpriced for what it is, but it has been rock solid for streaming via both Jellyfin and Plex.
The official Jellyfin app is definitely not as polished as Plex, but it has consistently worked for me on the Shield.
