Just for fun, I tried to run some simple timing loops in Pythonista. They take about the same time as on my 2017 15" MBP . For comparison, they take about 4 times as long on my old 9.7" pro. Unfortunately, Apple does not allow Pythonista to use multiple cores. With 6 cores it should run circles around my 4 core MBP. What I don't understand in the context of this is why so many of my apps run slower on the iPad than on the MBP.
