Understanding the parallel shape

We already know these operations can take a long time and don't want this to slow down our processing as it could create long delays that are the aggregated processing time of each operation. We know there is a parallel shape that we can use:

1. Drag a Parallel Actions shape onto the canvas of ReorderCalculations and name it Calculate Reorder Size.
2. Right-click Calculate Reorder Size and select New Parallel Branch.
3. Drag each of the expression shapes into one of the parallel branches putting small on the left, medium in the middle, and large on the right.

If we deploy and run our solution again we see the exact same output as before. The parallel shape did not parallelize our solution at all. In reality, the parallel shape ...
