Sorry, by objects I meant Components.
The components aren't that large or complex. They simply display an image
and a few labels based off the information off the record being passed to
it.
<mx:Canvas x="0" y="0" height="100%" width="100%">
<mx:Image source="{src}" width="125" height="125" x="0" y="15" />
<mx:Label htmlText="{nameItem}" x="0" y = "0" fontWeight="bold"/>
<mx:Label text="${priceString}" x="135" y = "50"
fontWeight="bold"/>
</mx:Canvas>
The XML file is about 2700~ records, which turns out to be around 2.7mb.
I've got IIS compression working on it so it brings it down to about 200k.
It's not a load issue with the XML file, as I can load the XML in to a data
grid near instantly. The issue seems to be the creation of the Components.
The way I've got it set up now is by loading and displaying the first 9
records. However, that removes the scroll bar, thus not allowing the user
to browser all the records
quickly.
What do you mean by "remoting"?
Thanks!
Luke
