Scaling Simple Mathematics
When you’re looking for scaling opportunities, simple mathematical changes are often suggested. Such simple changes for a single instance seem unimportant. As use of the application increases, they can have a huge effect. It is easy to kill an application by millions of small cuts. A test of addition, subtraction, multiplication, and division for both integers and floats shows interesting results, as shown in Figure 1-4. What is more scalable in one language is not always more scalable in another.
