Now, we have learned about various compiler optimization techniques, and they are really great, so we don't need anything else, do we? Unfortunately, there are limits to the optimization the compilers can do, and these limits stem from the fundamental compiler limitation, which is that the compiler can see only one file at a time! This restricts all of the optimizations to the contents of that file only, and everything that happens in other parts of the program is like black magic to the compiler. We have already seen the pessimizations the compiler is forced to do when it sees an external function, haven't we? So, there are many optimization opportunities which have to be omitted because of the narrowed view the compilers are forced to take. What we need is whole program optimization (WPO), but how can we achieve that? One possibility...

Overview of this book
Achieving efficient code through performance tuning is one of the key challenges faced by many programmers. This book looks at Qt programming from a performance perspective. You'll explore the performance problems encountered when using the Qt framework and means and ways to resolve them and optimize performance.
The book highlights performance improvements and new features released in Qt 5.9, Qt 5.11, and 5.12 (LTE). You'll master general computer performance best practices and tools, which can help you identify the reasons behind low performance, and the most common performance pitfalls experienced when using the Qt framework. In the following chapters, you’ll explore multithreading and asynchronous programming with C++ and Qt and learn the importance and efficient use of data structures. You'll also get the opportunity to work through techniques such as memory management and design guidelines, which are essential to improve application performance. Comprehensive sections that cover all these concepts will prepare you for gaining hands-on experience of some of Qt's most exciting application fields - the mobile and embedded development domains.
By the end of this book, you'll be ready to build Qt applications that are more efficient, concurrent, and performance-oriented in nature
