Some people love saying Mastodon/OStatus is very scalable because of federation but let's be honest that's some bullshit. It's easy to split and multiply, but that's not scaling.
The birdsite is much easier to scale.
Just imagine one edge case we're not seeing for now: many people using it (let's say millions) and following a very famous person
That person must have their own instance at this point, at least.
... what happens when they toot?
just imagine the enormous peaks and lag it'll do. And we're not even talking about media.
How would Mastodon realistically handle Katy Perry? I have no idea.
@CobaltVelvet I'm surprised this (current?) limitation is rarely brought up in the news article about Mastodon. Or being more openly discussed by developers.
Any estimate of the max. number of toots/users/follows an instance can support?
@jeepfromoil I don't think there's any hard limit to the federation, it just gets more expensive. Each instance is individually as hard to scale as birdsite, except birdsite profits more from that continuous growing.
