Hi,

I'm interested in setting up Nginx server for image serving, mostly small images such as icons or thumbnails.

Usually I use Linux, but I understand that file AIO doesn't work on Linux. A few questions:

1) How much performance increase does file AIO realistically provide for file serving - 10%? 50%? 100%?

2) If the performance increase is significant, which OS do you recommend for file AIO - FreeBSD, NetBSD, Open BSD, OpenSolaris?

3) Is it a steep learning curve moving from Linux to one of the aforementioned OS?

Thanks.
