WPF control performance

Question

What is a good (and preferably simple) way to test the rendering performance of WPF custom controls? I have several complex controls in which rendering performance is highly crucial. I want to be able to make sure that I can have lots of them drawwing out in a designer with a minimal impact on performance.
