Is RM6 designed to run on single, dual or quad processor cores?

What prompts the question?
I doubt RM6 is designed to use more than one processor. Even though the Delphi platform can support multicore, I think the developer has to include controls to detect their presence and take advantage of them and that would be extra effort... There is no mention of multicore that I can find in connection with the database engine DISQLite3; maybe it would be illogical to have multiple connections to the database file.

In the absence of any benchmarks, I seem to detect a performance boost by aligning the affinity of RM to only one core.

How do you do that?
You are using a SSD, iirc? I wonder if core affinity is of greater effect given the high speed drive.

SSD ... yes. To set affinity on an ad-hoc basis, open Task Manager and select the Processes tab. Highlight the RM executable, then right-click and select Affinity menu item. De-select <All Processors> and select one of the individual cores. Setting affinity on a permanent basis involves appending the target command-string in the application shortcut icon.
