massive improvement in instantiation speed it is still probably the
issue in 2.0.
As you noticed, getting the data back is quite fast, so why not load up
a local data store, and then use paging techniques to display the data?
Matt Chotin has a treatment of the large data set issue on his blog.
Also, depending on your use case, consider using a list with a custom
renderer, particularly if you don't need the DataGrid's column
resizing/sorting functionality.
This issue also shows up using a repeater: Rendering 100 complex items
is unbearably slow, while doing 5, with page-up, page-down is blazing.

Subject: [flexcoders] Number of records in a Datagrid
Hi,
Does anyone have an idea of how many records in a datagrid are to many?
I have a situation when the Flex2 SWF loads, the it hits the DB and
retrives records.
If I am retriving 100 records it takes about 2 seconds.
If I am retriving 15000 records it takes more than 3 mins, even though
the CFC is completing the call to the DB and returning the records in
2 secs.
I am running all this locally on my system, so network speed issues
are not a consideration.
Anyone else had issues with large queries?
Cheers,
David
