Lemmy Performance / Scalability (lemmy.ml)

In the sign up process, it discourages using the primary srever. In the docs it talks about performance limitations. In contast Mastadon does not do this. Worse yet, most people think of a single centralized server. And this server only has some 500+ active users a month. Maybe 10 times that many lurkers?

While I love the Lemmy design, and the community looks great, I fear that it does not scale. Worse yet I suspect that the Activity Pub protocol is grossly inefficient for Reddit style applications. Maybe a publish subscribe message broker, like MQTT would be much more efficient.

So what is gong on here. Is this an issue? Am I correct to be scared about Lemmy scalability.

And just for context, I think you are totally on the right track, way ahead of all ofther reddit clones, but maybe just a little off course. Can you crank up performance?
