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

Qt Performance on Embedded and Mobile Platforms

This chapter will go over specific performance considerations pertinent to two relatively new platforms that Qt is expanding to from its originally desktop-centric focus, namely the embedded and mobile platforms. Using our hard-won knowledge from the previous chapters, we will look at networking challenges on mobile devices and problems with resource and graphic constraints on embedded ones.

You do not have to know a lot about embedded and mobile development, as we will first introduce both subject areas.

However, we won't provide a detailed introduction to mobile and embedded development, as we would probably need an entire book on its own for that. Our goal here is rather to provide a basic overview of both fields and then discuss the performance-relevant themes that can be encountered there.

In this chapter, we will cover...
