  1. The top function takes 50% of the runtime,
  2. and that means that even if you made it go to 0 time,
  3. the program would only go twice as fast.
  4. So you'd get a 2x speedup.
  5. The top 3 functions between them take 50%, 20%, and 10%,
  6. or 80% of the total time.
  7. So if you were to make those all drop to 0,
  8. the program would be taking 20% of the time that it used to take
  9. and you'd have gotten a 5x speed up.
