I'm interested in POSIX AIO support, so I would like to know if with the aio module Nginx performance is better then simply increasing the number of worker processes.

The current AIO module is network AIO only and works under FreeBSD only. It's not maintained and now may not work at all. FreeBSD's AIO network support is unenfficient (no zero copy and not scaleable) and buggy (when I developed module I saw kernel panics several times).

There is still no disk AIO support.
