AEM provides a DataWindow data cache mechanism for caching the frequently used DataWindow data. It is recommended that you enable the cache for the DataWindow objects whose data is relatively static. Any DataWindow objects whose data is fairly dynamic should remain unchecked, otherwise you will experience overhead from the caching mechanism without the true benefits of the caching.
NOTE: DataWindow Data Cache will not be effective until you fulfill all the configuration requirements that are detailed in the section called “DataWindow Data Cache” in PowerServer Configuration Guide for .NET or in PowerServer Configuration Guide for J2EE. Also, this feature is only supported on Windows servers.
