Check out my articles on working with large data that are on my blog. http://weblogs.macromedia.com/mchotin. You are seeing the exact problem of downloading lots of data. The time spent with the cursor not moving is the Player deserializing all of the data that comes back. If you only care about one field you will want to consider changing the data so that it is an array of just those values instead of an array of value objects. You may also want to consider paging.

I guess we are confused because the Onresult should only run when results are available. We added a timer to see when they are available, and they are in the first 2 or 3 seconds of the 10-15 that it actually takes to see the clock go away. If we ask for the length of the result, it is actually available in those 2-3 first seconds after the clock stops. However, any other process seems to go to a queue that runs after the 10-15 seconds, including using the results.

I had a similar problem and I ended up paginating the data. i.e. return the following object { items:Array; hasMoreRecords:Boolean; } Hopefully this helps --- Dmitry --- In [email protected], [EMAIL PROTECTED] wrote: > > > We are doing some searches using a RemoteObject and displaying the result > on a grid.
