BC server takes 45 min to come up

Question

I have a BC server deployed to 8i db. The GUI uses InfoBus and data aware controls and presents 8 tabs for displaying grids of various data types. There are approximately 5000 rows total of data associated with all of these grids. It takes about 45 minutes for the GUI to come up with all of the data. Why should it be taking so long? Is this too much data? The CPU meter on the database server (Sun box; 1 CPU; 500MB RAM) is pegged at 100% utilization for almost the entire 45 minutes until the GUI appears on the client.
How can I improve this performance while still using InfoBus and DAC controls? Docs say entity objects are created representing each row of data - are 5000 entity objects being created when the BC server starts up?
Any help greatly appreciated...

Hi Tom!
From our previous discussions, I think you've found that the issue stems from the fact that by default in a DAC form, all of your queries are executed when the form starts.
For the benefit of others who are listening in, one way to reduce this start up time is to delay the execution of the queries. This requires some modification of the wizard-generated code. The steps are below.
1.define the all RowSetInfo objects and their attributes
2.parent any RowSetInfo whose queries should be executed immediately to the SessionInfo object
3.publish the SessionInfo
4.parent any RowSetInfo objects whose queries should be delayed to the SessionInfo object
5.when appropriate, publish the RowSetInfo using RowSetInfo.publishRowSet(true)
