I'm loading about 2100 items in the treeview, top tier only, using incremental load for sub tier items. The tree takes about 20 seconds to load, which will be a pain point to the end user. I timed the server call to actually retrieve the 2100 items to populate, and that only takes about 1 second. The rest of the time is spent loading the treeview client side. Is there any way to make this faster? I realize that's a lot of items and it might be unreasonable to expect it to load in just a few seconds.
