It’s not a good idea and that’s where I’d really start with the dated commentary here rather than focusing on the polling mechanism. It depends on the application but if the buffers are large (>=64kb) such as a common TCP workload then uring won’t necessarily help that much. You’ll gain a lot of scalability regardless of polling mechanism by making sure you can utilize rss and xss optimizations.

It's been a while but why is uring not helpful for larger buffers? I'd think the zero-copy I/O capabilities would make it more helpful for larger payloads, not less

		uring supports zero-copy, but is not a copy-reduction mechanism; it is a syscall-reduction mechanism. Large buffers mean less syscalls to start with, so less benefit.
