Tuning Configured Applications for Virtual Screen Space

A Web application can render content beyond the limits of the data displayed on the screen, effectively increasing the amount of work done to render content without any user benefit. It is recommended to build user interfaces that render only content in the visible area of the user interface. Large rendered surfaces, the interpreted nature of the application, and the ability to adjust application functionality can compound and reduce the performance and response times of the UI. It is recommended that you review the deployment with a focus on optimized content.

In light of these considerations, review the following recommendations:

• Minimize the number of applets in a view. It is recommended both from a performance and usability perspective not to add more applets to a screen than the typical user can view or work with without scrolling. Scrolling interrupts work and does not work well on some mobile devices, and the content that is not displayed still must be rendered when the screen is refreshed.
• Minimize the number of displayed columns in a list view. Consider limiting and setting reasonable defaults for the number of columns available for list views. For most computer desktops, no more than seven columns should be displayed by default, as a rule of thumb. Even hidden components have to be processed by the rendering engine.
