Improve performance of WDA using Custom Controller

Hi all,

I am trying to improve the performance of a WDA not developped by me, I saw that into the WDA the assistance class missed and I created it and moved part of methods from the component controller there. Then as into the component controller there are all nodes and methods of the wda, I created a custom controller too, in order to move there part of nodes and so relieve the component controller, first question is, is this action useful to improve the performance?

Furthermore I would like to ask, as the nodes of component controller are used in a lot of methods of wda and it is impossible to intercept all of them, I replicated these nodes into the custom controller and mapped them to the component controller, in this way I thought the data is located into the custom controller and the component controller works with an instance of it, is this correct?

Thanks
