If you happen to be jumping between reports and dashboards it would save a great deal of resources if rather than have Adobe Auto execute the report view, it pulls up a sample of last view if in cache or ask you if you wish to run to get latest data if not cache exists.
This allows you to set the time you're intereste in apply your filters etc.
this would save so many useless calls being sent to the Data Center and improve response times for desired qureies.
