On: Using io_uring for network I/O

Sure, io_uring is better. IOCP still captured the biggest benefit, completion triggering.

Without the submission batching you lose your system call reduction and that is far and away the biggest benefit.

The way I see it, a bigger benefit is avoiding readiness-triggered IO. That can add a variable number of syscalls, wakes up threads, etc.

Of course, batching is also great.
