How resource intensive is the federation part of running a lemmy server? (lemmy.ml)

I ask generally out of curiosity. I was just thinking that as big social media fractures, old school isolated forums might become "cool again", and that one of the achievements of lemmy might be as a nice platform for simply running a forum for whatever community you want all without needing to worry about federation.

If it turns out that work of federating data is a substantial part of the resource overhead, and that an isolated server would actually be quite efficient, that'd be quite a nice feather in the lemmy cap I'd say. Hexbear seems to have been using lemmy this way for a while and it seems to have been successful too.

I run a single user instance and I subscribe to 47 communities from 12 servers.

Most of the time I see 3 requests per second from the other servers.

I'm running on the cheapest Hetzner VPS with aditional storage, because the 20 GB are not enough for lemmy and the OS.

The load is most of the time at 0.2

Not sure about resource usage but a single instance for a given community mean a single point of failure.

Even with federation the community is bound to an instance, so once the instance goes down the community is down too, at least the federation of the community as far as I understand. So it is already a single point of failure.

Why is that? That shouldn't be necessary, should it?
