The first request to ITP/OnLine (ASP.NET) may take significant time (sometimes even up to several minutes). This is due to the behavior of Microsoft IIS. Microsoft IIS uses worker processes to process requests. The worker processes are recycled after a certain time, certain number of requests, or after a certain amount of idle time. This behavior is configured and can be changed in the Microsoft IIS application pool. You can change the Recycle worker process settings in your application pool properties.
