Avoiding pitfalls and leveraging C++ features to minimize application latency

In this section, we will look at different C++ features that, if used correctly, can minimize application latency. We will also discuss the details of using these features in a manner that optimizes application performance throughout this sub-section. Now, let us start learning about how to use these features correctly to maximize application performance and avoid the pitfalls to minimize latency. Note that all the code snippets for this chapter are in the Chapter3 directory in the GitHub repository for this book.

Choosing storage

Local variables created within a function are stored on the stack by default and the stack memory is also used to store function return values. Assuming no large objects are created, the same range of stack storage space is reused a lot, resulting in great cache performance due to locality of reference.

Register variables are closest to the processor and are the fastest...
