When creating a custom DisplayObject, and placing a number of instances on the stage that will animate - does the amount of data stored and code within each instance have an impact on the speed to render those instances?

Imagine the instances visually contain nothing more than a thumbnail image, and the code and data that may be stored within the instances isn’t being executed while they’re animating - I’m just curious as to whether the weight of a complex class, per instance, effects the rendering performance/fps? I know the system memory increase with each instance, just looking for ideas on rendering.
