I have a php website hosted on IIS.
App pool idle timeout is set to 0.
Recycling is set to 3am daily.
After some time of inactivity (0 users on the website) First hit is very slow. (10-15 secods) vs normal 2 seconds.
I looked at the network tab in chrome and it shows that it spends most of the time on "Content Download" of js and css files (~500-600kb)
So, I'm wondering if there's a problem with static files, but not sure.
