Tree + lots of leaves = slooow

[npeel]

So I've been playing around with the ColumnUI tree example and I added a few hundred leaves to the first parent node. This makes the tree slow and unresponsive. I'm wondering if this is partly due to the animation that happens when you open a node.

Are there any other ways to speed up the tree?

Did you try http://extjs.com/deploy/ext/docs/output/Ext.tree.TreePanel.html#config-animate

I did set animate to false and it knocked about 33% off the time. I think I'll just have to break the data up into smaller chunks.
