Whenever you use Webform Server to deploy forms to a group of users, consider providing the Viewer to some of your users.
For example, your user base might include an external group (for example, your customers who are submitting applications) and an internal group (for example, your employees who are approving customer applications). In this situation, you can provide the Viewer to your employees.
If Webform Server detects that the end-user has the Viewer, then the XFDL form is directly served to the user without conversion to HTML. This will help reduce the loading of the Translator and increase overall performance.
