>The interesting one is that it is in form, or simply one modi view makes to delay proportionally to the size of the data of the table. Being that modi view would have to be independent of the size therefore it still it did not process nothing this only modifying the data of view.

I'm not understanding everything here:
You have a view, you put it in the form, ran the form it was quick, changed the view and now the form runs slow; the view now returns nothing?
