If they are 'unblended' (Blend = 0) that branch should not get processed. One way to check this approximately is to look at the node graph when playing back (Turn on the view 'v' I think), the active node(s) get highlighted as they are processed. I have a script that prints some basic stats on which nodes are using the most processing time which I will post when I am back at my desk.
Also look into Domain of Definition (DoD), optimising the amount of data you are processing can dramatically speed up processing in some situations, especially if you are merging large images and only using small parts of them. One example would be if you merged a 8K image at original scale over an HD image, Fusion could from then be processing 16 times more data than it needs to as it may display HD but would keep and process the 8K boundary around that.
I personally would love to see a crop option on the Merge node to prevent this.
