All,
We are using dojo Grid with CsvStore with around 30 records and 25-30 columns.
In IE, the rendering is pretty slow compared to FireFox.

but Sorting is very very slow in both the browsers.

Here is how we are creating the grid:

var wstore = new dojox.data.CsvStore({data:jData});		
var wjsonModel = new dojox.grid.data.DojoData ( null,wstore,{query:{ isActive :'*' }, rowsPerPage: 10, clientSort:true, jsId:"wmodel"});
var infoGrid = "wGrid");
infoGrid.setModel(wjsonModel);

And here is the view definition:

var fixedColsView = {
noscroll: true,
