ClearAndLoad is very slow with IE and a complex xml data

Hello,

When I use the “clearAndLoad” function, it is very slow to run with IE and a complex xml file.

Firefox and Chrome performs this function in 2 seconds (with the latest versions of the browser).
IE performs this function in 18 seconds (I tested with IE8 and IE 11).

How can I improve performance with IE?
I have attached an example.

In advance thank you

Unfortunately it is not available to increase performance of the grid in case of such big number of columns.
For the dhtmlxgrid it is recommended that the number of rows should be greater the number of columns.
