The client application is comparatively lightweight, so I think you can generally expect better performance for data intensive tasks with N server processes instead of N-1. Note, you can run more than N if you wish, but you likely will see performance degrade sharply.
Of course how it scales in practice depends greatly on the problem. What ParaView scales well at is data intensive problems, where it benefits most because there is N times the available RAM when it is run on a cluster with N nodes, an to a lesser degree on having N CPUs to run through the data.
