Using an assembly to render many actors is possibly the slowest way of
doing this.  I know because I just wrote a simple test script.
Instead of using an assembly either add the actors directly or better
still use the vtkAppendPolyData class to do the job.

I've attached a simple test program to demonstrate how you can test.
