Hands-On High Performance Programming with Qt 5

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

Further reading

There are several books about specific C++ performance techniques. We already mentioned two: the slightly older Efficient C++ Performance Programming Techniques by Dov Bulka and David Mayhew (Addison Wesley, 1999) and Optimized C++ by Kurt Guntheroth (O'Reilly, 2013). Both books discuss basic C++ optimizations in more detail than we are doing here and contain a fair number of general performance techniques. There are also example implementations of custom memory management techniques and, in the second book, there are also STL allocators.

There is also a newer book focused more on the recent C++17 language version: C++ High Performance by Viktor Sehr and Björn Andrist (Packt Publishing, 2018). These books focus more on C+ usage in a standard setting, that is, without using Qt.
