Dhtmlx tree - loading takes lot of time in IE

I have a static tri-state dhtmlx tree. When there are huge no. of nodes in the tree the performace goes down drastically, specially in IE it takes around 1-2 mins to load a tree with 1000 nodes.

Can anyone help me on this, I cannot make this tree dynamic since I have to maintain the state of each node whether it is checked, unchecked or partially checked. User checks some node and saves the form and when user comes back to the same form he should still be able to see the selections he made.

In Firefox it take 20-30 seconds but in IE it takes hell lot of time. Please le me know how can I improve it?


you can try to use Smart XML Parsing to improve performance:
