That is an area I am curious about as well, especially if you throw io_uring into the mix. I think most kernel bypass solutions get some of their gains by just forcing you to use the same strategies covered in the perfect locality section. It doesn't all just come from the "bypass" part.

Even if isn't quite as fast as DPDK and co, it might be close enough for some people to start opting to stick with the tried and true kernel stack instead of the more exotic alternatives.

My gut feeling with io_uring is that it wouldn't help as much with messaging applications with 100 byte request/reply patterns. It would be better in a with a pipelined situation, through a load balancing front end. I would love to be proven wrong, though.

1.2M req/s means 2.4M (send/recv) syscalls per second. I definitely think io_uring will make a difference. Just not sure if it will be 5% or 25%.
