It is basically just a normal computer and I feel you’re optimising the wrong thing here too given we’ve already established the OP was wrong when they threw around what they believed to be the applications file sizes.
Indeed. If you are so concerned about memory usage that a 20MB app is so bothersome, why would you be running a 1+GB platform? The pi is the pi. No need to fret about optimizing down from 3% memory usage to 1%.
