How does having multiple lemmy servers spread the load? in c/selfhosted@lemmy.world

Interesting, I thought every social network that implemented the ActivityPub spec behaved in exactly the same way. Thanks!

This means that if user 1 from server A requests a post from server B, server A will cache that post. Then, if User 2 from Server A wants to see the same post they get the cached version instead of the remote instance pushing it to server A? Is this cache eternal (i.e it is never deleted from Server A) or is that something the spec doesn't address and it is up to each server owner?

How does having multiple lemmy servers spread the load? (lemmy.world)
 

Basically, I have read several statements addressing this topic. For example:

"If my server gets too big I will just close registrations"

"Server X got too big, so they closed registrations to manage the load"

While I do understand that this can help for small servers which don't have a big number of external users. How does this help with big and popular servers? Don't they have to serve requests from external users using their resources? For example, I might self host a server just for my account but I read all my content from lemmy.world. Am I not using their bandwidth and their resources anyway?

Bonus question: Does federating with other servers increase the resource usage of my server? What kind of metadata/data do I have to store from each server I federate with?

Thanks!
