The posts in Kbin don’t seem to move much the last few days I’ve been using it, but if I go somewhere like lemmy.world the content is always pretty fresh
Is KBin just slow or is there something fundamental I don’t understand about federation? (Likely)
How much data is pushed through ActivityPub? Unless it is at least tens of thousands of requests/events (i’m not familiar with how it works) per second I doubt that the choice of language would have big impact. PHP is made specifically for web backends after all.
Yeah. PHP is not a speed limiting factor unless you’re calculating Pi to X million digits. Almost everything about ActivityPub is limited by network IO.
