I really need to display 10,000 children under a treenode, the perf is really slow. Most answers I get suggest put them into multiple levels and use lazy loading.

I'm using lazy loading, and it really need display 10,000 children once. Is there any other solution to speed the expanding?

*displaying* 10.000 nodes means to generate 10k DOM elements, which will bring the browser to it's limit
(and probably the users too which have to scroll her way though that huge list ;-)

Fanvcytree may be a bit faster, but I don't think fast enough either (altho there may be paging support sometime later).

If you have that much data that you cannot categorize into sub-folders, how about using a grid control?
