EVERY video is slow. Dunno what to tell you. Maybe it's because I'm on the arse end of the world, but it's always a crapshoot whether or not a peertube video will actually load for me or not. Even this one buffered for ~30 seconds before it started playing, which is just too long for it to be a viable yt replacement just yet. I'm getting > 100 mbps down on this machine, so it's not my connection

ETA: I will say, after writing this, I tried a few others, and it does seem to be better than the last time I tried it, so maybe this was hasty. They do still buffer much more than yt, but they seem to play consistently now at least
