10 length only numbers and letters (uppercase and lowercase) = 10^62 / 4508 per second = 7 × 10^50 years
10 length only numbers and letters (uppercase or lowercase) = 10^36 / 4508  per second  = 7 × 10^24 years
10 length only numbers = 10^10 / 4508 per second = 616 hours

So yeah, 10 length numbers and letters is not going to happen.
