Unanswered: performance issue to expand tree panel if there are more than 20,000 nodes?
I am facing a performance problem for TreePanel now, we have more than 20,000 nodes( depth is 3 - 5 ), when we expand all node, there is an alert popup "Stop running this script? A script on this page is causing your web browser to run slowly, ......". And it takes about 5 minute to finish the operation. Is there any way to resolve this problem? Thanks for any valuable answer or clue!
dont load all the nodes at one time, load it by async RpcProxy when you click one node
