I don’t have the quantitative metrics, but I will say that I had the flu last year and I just laid on the couch with my steam deck and streamed cyberpunk using Moonlight. The latency was imperceptible to my flu brain, and it was a much better experience than playing for an hour at a much lower quality natively on the deck. I have a friend who also streams his desktop to his Apple TV (hardwired desktop, wireless Apple TV) and he beat metal gear solid V like that.
One thing that I do, though it may not be as secure as a reverse proxy is just using tailscale funnel to expose my jellyfin instance.
I’d like to learn a self-hosted SSO but time is my least abundant resource at the moment.
