Grid is implemented using a HTML <table>. 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(). -- J. Am Montag, 17.
