Delivering high-performance applications not only requires care for performance but also systematic effort to measure, test, monitor, and optimize the performance of various components and subsystems. These activities often require the right skill and experience. Sometimes, performance considerations may even bring system design and architecture back to the drawing board. Early structured steps taken to achieve performance go a long way to ensuring that the performance objectives are being continuously met.

In the next chapter, we will look into performance optimization tools and techniques.
