Performance Recommendations - User Interface

Recommendation

Description
AWT Runtime An optimized AWT application has performance advantages over JSP. Tomcat and the Browser (rendering process) reduce the performance in the JSP runtime.
Instantiate widgets only once To instantiate widgets is time consuming so it improves the performance when you store the instances.
Use CardLayout Use the CardLayout to switch between pages when the application has not many different pages. CardLayout requires some memory, so for a large number of pages in an application it hs to be evaluated.
Use LayoutManger carefully LayoutManagers are not always necessary. PDA screens have a standard resolution, so resizing is not an issue. If LayoutManagers are used avoid GridBagLayout.
