Is there any possibilty to have Async IO support in nginx-0.5.0?
I really need this to serve images.
What AIO do you mean - the disk file AIO or socket AIO ?
nginx currently supports socket AIO on FreeBSD only. However, the code
is not maintainable because the socket AIO in FreeBSD is not scalable
and kernel may even panic. As I understand vanila Linux kernel has
no socket AIO.
nginx does not support disk file AIO. I have plan to support, but
it would not be soon. To decrease disk latencies you can increase number
of worker processes.
