Comparative speed in switching among groups

[David Epstein]

Does anyone have practical experience or an understanding of the engine that would cast light on the relative speed of some alternative ways of doing things?  I want to switch among a number of different groups, each of which may contain its own fields, graphics, buttons, and images.  Possible approaches:

- Have many different cards, each with a group peculiar to it, and GO TO each card as desired, or

- Have one card, with many different groups, and SHOW/HIDE the groups as desired, or

- Have many different cards, each with a group peculiar to it, and COPY a group from an unseen card to a single card that is always seen (and DELETE the unwanted group on that single card).

There are other considerations that affect a choice among these methods, but my concern here is the speed with which I can switch from displaying one group to displaying another.   I am wondering whether at some level these methods all amount to the same thing from the engine’s point of view (since everything is in RAM in any case).

Many thanks.
