Does too much data binding make WPF application slow? What are the optimization techniques that are available?

I have completed a project on WPF? I wanted to know which are the possible techniques to optimize my code especially XAML and Data binding.

Tric开发者_如何转开发ks to have efficient data binding.

Please note I am using MVVM architecture.

MSDN contains a nice WPF optimisation article here - http://msdn.microsoft.com/en-us/library/aa970683.aspx, with a section specifically on data binding here - http://msdn.microsoft.com/en-us/library/bb613546.aspx
