I really really wanted to prove SOCKMAP rocks. Oh, well. Not just yet. In one of the linked videos the SOCKMAP authors say they didn't optimize part of the code. So there definitely is plenty of room.

I don't see any fundamental reason why SOCKMAP wouldn't be fastest. It's just a matter of putting an effort into it.

For example, we noticed the poor splice(2) performance is due to a spinlock. We need to figure out just why this happens, but it doesn't seem like a major problem. Probably just a trivial regression.

I really appreciate the effort you put into doing the benchmarks. Reading the first half of your article I was excited but also slightly dreading that I'd have to go to the trouble to create and run the benchmarks to see if it was worth the effort.
