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.

Lemmy uses PostgreSQL, with a number of tables. It's pretty standard stuff, looks like, and it's in Rust. It's assumed there's only going to be one server per instance right now, but I'd expect that one server could keep up with a reasonable volume.

Is that a typical number of users to have already? Wow, we really are growing.

Rate limiting is it's own thing, I guess some work will need to be done to find a non-exploitable way to do it that still scales.
