• Zones: For better performance, user interface zones should be initially collapsed when not required for 90% or more of business processes. The initial state of zones (collapsed or not) can be controlled via the Portal Preferences tab on the User portal.

• Number of Records: The number of records returned to the user interface for a zone should be limited to 50 rows when building custom zones against large transactional tables.

• Screen Troubleshooting: To troubleshoot a screen in the user interface, click Preferences in the top right corner of the application and choose the Portal Preferences tab. Choose the appropriate portal and set all zones to "Initially Collapsed". Navigate back to the screen that has performance issues, expand the zones one by one, and measure the execution time of each zone. This should be an accurate step-by-step representation of the full screen execution.

• Performance Optimization: For optimal user interface performance, laptop users should ensure their computer is in high performance mode.

• Solution Updates: Oracle should be consulted before significant solution changes are made. For example, configuration and solution extensions, adding a large number of customers, network changes, new integrations, etc.
