I first used lemmy on lemmy.world but due to its size I had several issues of things just not loading and needing a full page refresh. So I tried to set up my own instance and it works mostly but the federation aspect is leaving me with a few questions.
Will remote communities only sync new posts from when I subscribed or will past posts show up eventually?
Is having a single user instance realistic or should I try find another small instance?
Ruud, who runs lemmy.world, was asked how much the instance is using, see here: https://lemmy.world/comment/784410
Basically 30G DB and 60G pictrs for the whole instance for 4 weeks of usage.
They have 13k communities and 22k active users per month.
