I should do an updated version of that deck with io_uring and sans the PyParallel element. I still think it’s a good resource for depicting the differences in I/O between NT & UNIX.

And yeah, IOCP has implicit awareness of concurrency, and can schedule optimal threads to service a port automatically. There hasn’t been a way to do that on UNIX until io_uring.

Yes, please! And if you're interested, RegisteredIO and I assume you'd drop in IoRing.

In a nicely wrapped PDF :-)

Yeah I’d definitely include RegisteredIO and IoRing. When I was interviewing at Microsoft a few years back, I was actually interviewed by the chap that wrote RegisteredIO! Thought that was neat.
