I have a domain name that I own but am not making use of and was thinking of setting up my own personal Lemmy instance, partly so I can have a Lemmy id and instance that I can completely control, partly so that I can contribute directly to my hosting cost, and partly because it might be fun to tinker with (or it might just end up being a pain; I’m still trying to figure out which is the case).
However, from this comment it sounds like, rather than contributing to horizontal scaling and easing the load on other servers, I might actually end up increasing the load on other servers by adding yet another server that the other servers have to talk to in order to keep my server updated on the latest comments and posts to which I am subscribed.
So given this, would self-hosting a personal instance actually make things worse for everyone else and thus be an irresponsible action at this time and/or for the foreseeable future? Because the last thing that I want to do is to inadvertently add a burden to the fediverse!
ActivityPub traffics are not that heavy. The activities are queued in the background and processed by a pool of dedicated workers, so no matter how long the queue, they should not bog the webserver down. Each entry in the queue does occupy some memory, but should be negligible.
I would say that an active users subscribing to a community using their own instance is actually generating less server load to the subscribed community’s instance compared to a user in that instance actively interacting with the community directly. But, if you subscribe using a personal instance but never actually use it (never logging in, never interacting with the community, never lurking in any discussion, basically forgot it exists), then yeah, you’re probably a dead weight, albeit a tiny one.
