What does it mean to balance requests across cores? To run T event loop threads/procs, where T is tied to the number of CPU cores? So like, a pre-forking, multi-proc, evented server?

I actually can't think of a case where a multi-threaded/forking-only web server would be faster than that. Again, assuming complete support for async libraries used throughout the web application.

Are there any web servers that have this architecture? NodeJS obviously doesn't. *

* Actually, for maximum absurdity, it looks like Kore, the web server we are currently discussing, has this architecture
