There's some great information about IOCP vs. the various methods used on Linux (sans io_uring).

I should probably do an updated talk/article/deck on io_uring.

I really do like NT internals though.

I would love it if you did! You're actually one of the few sources that shines a bright spot on what the NT kernel is good at, outside of the ex-Sysinternals folks.

Is there any good article on NT internals (that isn't Russinovich' book), that highlight where/how it is better than Linux and other *BSDs?

When asked people point to IOCP vs epoll, but I'm not sure how relevant it is now that Linux has io_uring.

(They also point to stable ABIs for drivers, but I am more interested in internals)

Interestingly io_uring was added to NT.
