Using Properties to Improve Picklist Performance
To cache the content of certain picklists for subsequent use in the same user session, the property Cache Data property should be set to TRUE for the PickList Generic business component. By default, this property is TRUE.
NOTE: Picklists based on PickList Generic display LOV data, which is unlikely to change during the user session and are thus suitable for caching. Picklists based on other business components display data that could change during a user's session and is thus generally unsuitable for caching.
Also set the Long List property to TRUE for each applicable Pick List object definition. When Long List is TRUE, the focus is not maintained on the current picklist record, thus improving performance for picklists with many records. The default setting of Long List varies for each Pick List object definition.
