ASP.NET: Why does it take forever to load a page after compiling?

Question

Why does it take forever for ASP.NET to process a request the first time you try to access the site after compiling?

Maybe it's just me but the first time I visit a page after I've compiled my project, it takes about 20 seconds before I receive a response. Why is this?

Answer 1

This is because the pages are not completely "compiled" until you run them for the first time.
