Does Nginx block on file IO?

May 01, 2011 08:26PM
Hi.

I was always under the impression that Nginx is non-blocking for file IO. Then I was told it wasn't.

I'm considering using Nginx to serve static images. Pretty much every connection will result in a file IO. If Nginx blocks for file IO, then using Nginx here wouldn't be any better than using Apache, right? Every connection will lead to a file IO which blocks the entire Nginx process. So to serve 500 concurrent connections I'll need 500 Nginx processes.

Would Nginx work in such a use case? Any tips on how to use Nginx for serving static media?

Thanks.
