Form data population and extraction
For forms that contain a data model (XForms or XML Model), do not populate data or extract data for individual elements:
Disable Viewer detection if not using Viewer
By default, the Front End Application will detect if the end-user has the Viewer installed on their system. If you know that none of your users have the Viewer, you can improve performance by disabling automatic detection.
Use Server Speed Flags
If you are developing a Front End Application using the IBM® Forms Server – API, you can significantly improve performance by turning on the server speed flag setting in the readForm method.
