multiprocessing - Is it better to have one Pool for more functions in Python?

Question

I'm using multiprocessing.Pool in 2 function that run sequentially. I create the Pool in the first function and when it terminate, I close it and open it in the second.

Ex.

def first_function():
   pool = multiprocessing.Pool()
   .
   .
   pool.join()
   pool.close()

def second_function():
   pool = multiprocessing.Pool()
   .
   .
   pool.join()
   pool.close()

Is it more efficient to create one single Pool before the 2 functions start and then pass it like argument?
