Severe performance degradation with IE 8 smartscreen filter

Suite and Optimus Suite 5
#1

We do not see any issues with any other Browser, IE 9, or pre IE 8.

However, with the filter on the parsing time goes from 5 seconds to 32.

Here is a portion of the code:

tree = new dhtmlXTreeObject(“treeboxbox_tree”, “100%”, “100%”, 0);
tree.enableCheckBoxes(true);
tree.setImagePath(“dhtmlxTree/imgs/”);
tree.loadXMLString(data);

where data is a very long xmlstring with a large number of nodes.

if you have professional edition, you may try to enableSmartXMLParsing. In this case nodes will be parsed (rendered) only when it is needed (top level nodes and open nodes).

This functionality may improve performance.
