It seems that self hosting, for oneself, a federated service, like Lemmy, would only serve to increase the traffic in the network, and not actually serve the purpose of load balancing between servers.
As far as I understand it, the way federation is supposed to work is that the servers cache all the content locally to then serve to the people that are registered to that server. In doing so, the servers only have to transmit a minimal amount of data between themselves which lowers the overhead for small servers – this then means that a small server doesn’t get overwhelmed by a ton of people requesting from it. Now, if, instead, you have everyone self hosting their own server, you go right back to having everyone sending a ton of requests to small servers, thereby overwhelming them. It seems that it’s really only beneficial to the network if you have, say, hundreds of medium sized servers instead of, say, thousands, of very small servers. While there is the resilience factor, the overhead of the network would be rather overwhelming.
Perhaps one possibility of fixing this is to use some form of load balancer like IPFS to distribute the requests more evenly, but I am no where even remotely close to being knowledgeable enough in that to say anything definitively.
I can only speak on behalf of Matrix Synapse, but enabling Federation and joining the matrix.org destroyed my server with a i5 6600k- it is very expensive to federate and the resource cost per user is very high if you’re not sharing your instance with anyone.
I was running a federated synapse on a much lower spec’d machine than that … and it was fine. I don’t think it’s federation that does it, it’s joining large and active groups.
Yeah, that’s what I said.
Have you tried conduit? I am joined to rooms with several thousand users each, and I’m not really suffering any slowdowns except during initial sync. Conduit seems to be running happily at half a gig of RAM, and CPU usage is minimal
I haven’t bothered because nobody I wanna talk to is on Matrix, anyway :P
