Async Data Load in Grid

I am trying to figure out the best way to load a large dataset into the grid asynchronously. My current script takes too long to render the huge javascript array so I'd like to load the page quick and feed the grid chunks of data. Is there a better way to do this other than set up a timeout and grab the chunks via HTTPRequest and then call AddRow on each one?

Are you using the Grid's Virtual Mode?
