Adding many fields to a form gets slower and slower

Hi together,

I have a method adding fields via Document.Form.Add(Field field, int pageNumber).
The first fields are added inner milliseconds. At all, I add more than 200 fields. After 100 fields it takes more than 500 mseconds for adding and later more than one second.
I think something is calculation all added fields everytime and that needs time.

Is there a possibility to add more than one field ore to recalc only on demand during adding.

If you need an example please write …
