Improving Startup Performance

Macromedia Flex provides settings that let you determine when controls and other components are created when you invoke a Flex application. You can use these settings to reduce the startup display of your applications, or stagger the display so that parts of the application appear before the entire application loads.

Flex also lets you hide the children of a Panel container when resizing the container. This lets you avoid the jerky animation that can occur when Flex cannot update the screen quickly enough.
