    I'm looking for some advice on where to start debugging an issue.  It's a little weird, and we can't reproduce it in out environments, but our customer is reporting it, and it's becoming a big deal for them.  So this is more of a consultation rather than a complaint or a bug report.. So this is the issue: they're using a TreeView-based control, and the tree view is configured to use Load on Demand with LazyLoad.  The client response time is taking 3-5 seconds, and there's not that much data coming back.  I know this isn't much information, but any pointers on where to start looking would be much appreciated.

    Thank you!

    Hello Dasha,

    I would like to recommend you checking our online demo that demonstrates performance optimization using WebServices with lots number of nodes. You may also review the rest of demos in the LoadOnDemand section and compare their implementation with your approach.

    Hope that this will lead you into the right direction.
