jQuery Grid Plugin - jqGrid

I'm looking for recommendations for jqgrid to add a large dataset from a local source.   Right now, there's a simple loop:

   grid.clearGridData();
    for(var i = 0; i < data.length; i++)
    {
        grid.addRowData(i+1, data[i]);
    }
    grid.trigger("reloadGrid");

And on some larger data sets, this causes the browser to display the "javascript is using too many resources...quit/continue" message in IE and FF, usually after several "Continues" everything is fine.  This is for data sets of ~2000 rows. 

I can break this up into several chunks with setTimeout, but that feels kludgy.

Using version 3.3 of jqgrid.
