I am curious - does adding a portal to a layout increase response time on the layout? What I'm wondering is - when adding/updating records in other tables from any given layout - if it is generally better to A) go to a layout that contains the records I want to add/update only when needed, then switch back to my original layout, or if it is better to B) create portals out of user view and use those to create/edit records in another table when needed. Or is the difference negligible and simply developer preference? I know there are variables that make this question impossible to answer precisely, just wondering what the general rule (if any) might be. Ex. one or two portals OK, five would create a drag. One portal with five fields would be fine, 20 fields would show some slowness.
