I have nginx configured with
and no special prep on the OS side.
I tested loading lots of small jpegs from multiple clients, but there was not much of a different between aio on and aio off.
I'm not sure if I need to enable AIO in the kernel or not. How can I confirm whether nginx aio is working or not on FreeBSD? What would happen if nginx was configured to use aio but the FreeBSD kernel did not support it?
I'm using FreeBSD 8.1 and nginx 1.2.7 and the filesystem is UFS
