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

Cheapest Hetzner ARM64¹, 72 communities from 14 servers:

¹ CAX11: 2 vCPU, RAM 4 GB, Disk space 40 GB

edit: Weekly CPU usage is also pretty low:

Oh you went for the ARM CPU? I was looking at it but then I thought that there is no ARM docker container for lemmy, was I wrong?

The Lemmy Easy Deploy script available at GitHub supports Arm64 in theory. In practice, some required binary refused to run on my Pi 4 so I think it's still a WIP.

The Lemmy-Easy-Deploy maintainer gave up and created their own docker build for arm64 ;)

Thanks for sharing this!

So how are you making it work?

[–] [email protected] 1 points 1 year ago (1 children)

I am running it in a VM now, using Linux and Docker.

I meant if you're building the ARM version yourself or where are you getting it from?
