@katco Yeah, it is. I think it’s a combination of the protocol and the multi-tenant aspect that creates the bottleneck but I do see your point. For the single-tenant Small Web stuff I’m working on, I was running experiments with WebSockets – which are so lightweight – and I could run hundreds of thousands of them on a tiny instance (think: if we had constant connections between instances of one). Something like that would likely provide a very different experience, even with ActivityPub.
