You can use setTimeout() to process the XML in chunks, however, I would recommend using JSON or emitting script from the server, it will be much more efficient. Basically, you can avoid the slow script warning by yielding the CPU after processing a certain number of rows via setTimeout(). However, you will still face the issue that overall page load and startup will be slow.
It also depends on the visualization you plan to use. Most charts won't even render more than a few hundred datapoints without choking. Chronoscope/Timescope (http://timefire.com) is a highly specialized chart specifically engineered to scale to millions of points. -Ray On Thu, Feb 12, 2009 at 11:33 AM, Максим Барбул <[email protected]> wrote: > Hi, I think you'll have problems in displaying such big data store. > Try to split into pages or through out some points.
