When we display a large amount of data on the screen, we must keep that information in memory, which in turn means we must load a large amount of data from disk all in one go. It’s far better to break up an application user interface into consumable chunks of information than it is to try to display every last bit on the screen at once.

The careful use of tabs, sheets, and panels can improve the feel of a user interface, and that will in turn improve the performance. By splitting the user interface into smaller pieces, we have finer-grained control over what data gets loaded when, and we can reduce our disk access to ...
