Chapter 9: High-Performance C++
In this chapter, we switch focus from the optimal use of the hardware resources to the optimal application of a particular programming language. While everything we have learned so far can be applied, usually quite straightforwardly, to any program in any language, this chapter deals with C++ features and idiosyncrasies. You will learn which features of the C++ language are likely to cause performance problems and how to avoid them.
In this chapter, we’re going to cover the following main topics:
- Efficiency and overhead of the C++ language
- Learning to notice likely inefficiencies in the use of C++ language constructs
- Avoiding inefficient C++ code
- Optimizing memory access and conditional operations
