Grid is implemented using a HTML . HTML tables are slow in rendering
if you do not set table-layout:fixed; as a CSS property. You could also try
filling the Grid off screen, e.g. when its not yet attached to the DOM so
the browser has to do less layout/rendering.
If the above did not help then you simply push to much data into your Grid.
In that case you can take a look at CellTable / DataGrid which are meant
for handling this large amount of data. They achieve their speed by
minimizing DOM operations (which are slow in older IEs) and instead
building a huge HTML string and then set it using
parentElement.setInnerHTML().
