We are doing some searches using a RemoteObject and displaying the result
on a grid. We noticed that when getting more than 2000 records aprox, it
was taking some time( between 10 and 15 seconds) before they were
displayed . At the beginning we thought that it was the Grid which was
slowing down the process. We thought that because after making the call the
busy cursor ( clock) would stop, but would not go away for another 10-15
seconds, when we finally were able to see the results in the Grid.
However, we made another test. We simply made the call to the RemoteObject
and did not bind it to any component. We found that the 10-15 seconds were
still there, so we are wondering what exactly Flex is doing that is taking
that time. We also debugged our backend at we saw that the busy cursor
stops exactly when the server sends back the results to the client. So what
is happening in between?
Is this something related to serialization? Our RemoteOject returns a VO,
but we are only interested in one of the attributes that holds an Array. So
we do something like this...
var myDataProvider:Array = new Array();
Onresult ( result )
{
myDataProvider = result.myArrayAttribute;
}
myDatagrid.dataProvider ="{myDataProvider}"
Any ideas on how we can improve performance?
Thanks
