Microsoft has developed its own Linux: in-house software-defined networking OS

An even simpler summary: To add SPDY or HTTP/2 support to IIS, you must upgrade the operating system. I understand why this is (http.sys) but ... wow. Whereas using nginx I literally add "spdy" to the config and presto, double-digit% improvement on my site.

Yes exactly that sort of shit is what we have to deal with!

http.sys is a giant fucking turd. That and the whole urlacl thing. Nothing but pain. They added it because of shitty performance in the NT kernel when serving HTTP from userspace and it turned into a friction point for the whole operating system.

The question is why is the userspace so shitty? Doesn't Microsoft implement some async things into their kernel? Or stuff like epoll, kqueue, etc..?

NT syscall overhead is immense compared to a Unix derivative. There are layers galore.

I am not an NT guy so maybe this is off, but doesn't windows support overlapped IO? To my understanding it is a socket only version of epoll.
