formview

When i switch an ASP.Net Formview from readonly mode to edit mode it takes more than 6 seconds(from edit to readonly takes a split second). I have no idea whats the reason for it. The EditItemTemplate contains a lot of controls(table,textboxes,dropdownlists) but in fact not more than the ItemTemplate has. Yet i have even commented out the complete FormView.DataBound where the controls are data bounded but without significant change. My ASP.Net Web Apllication is using Ajax and the Formview is completely nested in an UpdatePanel. Any suggestions or assumptions for this behaviour?
