web app slow performance when leave idle for some time

Question

We have a web application deployed on IIS 7.5 target framework 4.0 the application perform slow when leave idle for few minutes for first time and then perform as expected t

Answer 1

The IIS application pool is shut down after 30 minutes of inactivity. After that, when you make a request IIS basically has to start the website up again, which leads to the behavior you are describing. You can change the idle time of your website in IIS though to avoid it.

You could also look into the Auto-Start feature of the 4.0 framework.
