Configuring IIS (v7.5) for ASP.NET application

Question

If I have IIS 7.5 or newer, and I want to make sure my ASP.NET application hosted on IIS is as responsive and available as possible, one thing I do is usually setting the Start Automatically advanced setting for the app pool in IIS to true :

My question that I'm scratching my head about (and can't seem to find a definitive answer for) is: if the Start Automatically = true is set, does the Idle Time-out (minutes) setting have any effect?

As far as I understand, the Start Automatically setting makes sure the app pool is always up and running and available - so doesn't that kinda "kill off" the concept of an "idle timeout" ?

Answer 1

Start automatically as the description reveals, only enables the application pool upon creation or when IIS restarts. It has nothing to do with the other setting.
