I have a native *.dmg Mac app which is using a lot of CPU and I wanna scale it. Is that possible?

Does it need to process more things per time? - YES Does it need to run on more machines? - NO Is it time critical / is responsiveness critical? - NO What are it's bottlenecks? Is it mem-bound? CPU-bound? IO-bound? - CPU What is "it"? - *.dmg software Is "it" connecting to something else, and what does "something" run on? - NO
