Are you saying io_uring is basically IOCP for Linux? If that's true, then I'm not happy about it being in the kernel. IOCP only goes 2x faster in my experience (vs. threads and blocking i/o) and that isn't worth it for the ugly error prone code you have to write. System calls are also a lot faster on Linux than they are on Windows, so I'd be surprised if io_uring manages even that.

Must be weird trying to explain why Windows had to introduce a new API that they've apparently already had for 30 years.
