Can we appreciate that Lemmy architecture design and dedication of instance admins made it possible for this to happen:
https://the-federation.info/lemmy
I wonder how many other projects could scale up this quickly as well as Lemmy did.
lemmy.world is the real hero. By far the biggest instance with open signups still
Sopuli accepted my account within 15 minutes, too. Nice to be on a geographically local instance.
Hijacking to praise “shit just works”, which is hosted on a very powerful system - twice as performant as Lemmy.ml
Lemmy is based on the “tokio” library which is a very efficient framework for asynchronous networking. This means that single instances are already quite efficient. That’s a good start for scaling. The other challenges might be the growth of the federation. No idea how it will develop, but since others (Mastodon) can do it I believe that Lemmy will shine there too.
Lots of people behind the scenes doing their best… and of course professional datacenters like Hetzner making it quite seamless to upgrade to dedicated hardware.
