Description
Tokio recently added tokio-uring, io-uring support for tokio.
io-uring is a new Linux API for asynchronous I/O operations.
io-uring makes filesystem operations truly asynchronous, and avoids epolls for events notification.
Some early tests claimed that by switching to io-uring, the performance of a simple TCP echo server improved by up to 60%.
Although io-uring is only supported on Linux kernel >= 5.6,
adding its support should improve shadowsocks-rust's performance with multiple clients.

Research direction
The issue names no files, tests, or entry points to begin with. Review the tokio-uring reference and the Linux kernel >= 5.6 requirement first; done would mean defining and implementing io-uring support in shadowsocks-rust and verifying whether it improves multi-client performance.
