In this unit, you ran the prototype. While the client does run successfully, it isn't efficient. While each individual client might not notice this with such a small number of stocks, that will change as the number of stocks grows and the number of clients pull from the server. The prototype can be improved. Let's learn how in the next unit.

But it becomes more noticeable as the number of stocks grows and the number of clients that pull from the server grows. The prototype can be improved. Let's learn how in the next unit.
