In this post I will show a few other tricks which can be used to improve the loading time even further. All techniques are optional and can be used independently. We start with a simple page containing only a single RadTreeView control with one root node. The testing environment is: Visual Studio 2008 SP1 Intel Core 2 Duo E6550 @ 2.33GHz.
