Slow postback after server event

I am using UpdatePanels and I have a tree with about 600 nodes that I populate from a hierarchical dataset.

I use the NodeSelected event to run some server code and create some html in a different updatePanel. If I limit the nodes to 10, the page posts back quickly. With 600 nodes it's quite slow -- about 5 secs. Can I optimize the tree for better performance? I'm still using the evaluation version. Does that matter?

Evaluation version does not matter.

If you do an async postback in UpdatePanel, then flytreeview state (that includes nodes, and all their settings) is posted back. And it may be large.

What amount data is sent with HTTP request?
