Run nginx under strace:

strace -f -e trace=io_submit /usr/sbin/nginx

You will see something like

[pid 1993] io_submit(139867403759616, 1, {{0x19a7ab0, 0, 0, 0, 10}}) =
1
[pid 1993] io_submit(139867403759616, 1, {{0x19a7ab0, 0, 0, 0, 10}}) =
1
[pid 1993] io_submit(139867403759616, 1, {{0x19a7ab0, 0, 0, 0, 10}}) =
1
[pid 1993] io_submit(139867403759616, 1, {{0x19a7ab0, 0, 0, 0, 10}}) =
1

if aio is working.

Thanks, now that I have it working, what particular files does it make
send
to send using AIO? Its interesting that in the example given here:
http://wiki.nginx.org/HttpCoreModule (see below) the location referes to
the
“video” directory, i.e. implying that AIO should really be used for
media
file delivery.

Would SWF files for example fall in that category?

location /video {
aio on;
directio 512;
output_buffers 1 128k;
}

What kind of test could be run to discern the advantage of using AIO on
any
type of file?

Thanks
