Chapter 2. Coding for Performance > Performance by Design

Performance by Design

This chapter has outlined a number of different places in the design process that impact performance. One way of visualizing this is to realize that there is a maximum possible performance for a given combination of system and problem to be solved. The choices made during design and implementation will either lead to the system meeting this maximum upper bound or cause the performance to be below this.

Decisions made early in the design process potentially have the largest impact on the performance of the application. The choice of algorithm can completely change the way the application behaves as the size of the problem increases. Similarly, a poor choice of algorithm can limit the scaling of the application as the number of available cores increases.
