I was playing with Tokio / Rust on MacOS and hit an about max 500k requests / second limit where the CPU was mostly doing send / recieve calls, not using MacOS asyncio system calls. I know it's a different library, and asyncio is not as flexible as io_uring, but at least batching send / recv calls from different sockets would be good to be able to do.
