How will lemmy scale? (lemmy.world)

I already get rate-limited like crazy on lemmy and there are only like 60,000 users on my instance. Is each instance really just one server or are there multiple containers running across several hosts? I’m concerned that federation will mean an inconsistent user experience. Some instances many be beefy, others will be under resourced… so the average person might think Lemmy overall is slow or error-prone.

Reddit has millions of users. How the hell is this going to scale? Does anyone have any information about Lemmy’s DB and architecture?

I found this post about Reddit’s DB from 2012. Not sure if Lemmy has a similar approach to ensure speed and reliability as the user base and traffic grows.

As far as I’m aware lemmy does not support load balancing or high availability as it currently stands. But development is still in its infancy and I’m sure that’s a top priority

I don't think it officially supports it but it does work! Lemmy.world is currently running on multiple containers load balanced by nginx. look at u/ruud latest post about it

It's not only about scaling a single instance, but scaling the fediverse.

Currently, each instance sends all events to all federated instances. That means, essentially each instance needs to store and process a significant part of the entire fediverse. That's insane and has to be addressed.
