You might occasionally experience a slow initial load time for web forms. This issue can also occur after a period of inactivity (around 2 hours).
However, once the form has been loaded, any other forms will load quickly.
This is due to the .NET compilation time, which occurs when:
- The form has been modified in the Form Designer, or
- The IIS application pool is automatically recycled. You can adjust the recycling frequency. See https://technet.microsoft.com/en-us/library/cc753179%28v=ws.10%29.aspx for more information.
