Io_uring, kTLS and Rust for zero syscall HTTPS server

This is impressive but it’s also an amazing amount of complexity and difficult programming to work around the fact that syscalls are so slow.

It seems like there’s these fundamental things in OSes that we just can’t improve, or I suppose can’t without breaking too much backward compatibility, so we are forced to do this.

I don't think it has to be. Conceptually it's just a couple of queues.

There's a software equivalent of the Peter Principle where software or an API becomes increasingly complex to the point where no one understands it. They then attempt to fix that by adding more functionality (complexity).
