Hi All,

I’m trying to understand the advantages of AIO and how using it with  
Nginx  
can improve performance.

I’ve compiled Nginx from source with the AIO option.

I’ve enabled AIO in my Nginx configuration.

How can I confirm that its working? If the server is serving pages,  
does it  
mean that its using AIO?

Thanks

What OS are you using?

I don’t think AIO works in Linux unless you’re using O\_DIRECT. But with  
O\_DIRECT you don’t get file cache.
