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

Optimizing Network Performance

We cannot imagine the world of today without ubiquitous wireless communication and instantaneous network access. Since Qt is not just a GUI toolkit but rather a general application framework, it has to support networking if it wants to stay relevant in the modern programming world. In this chapter, we will look at the performance of network protocols, the networking support to be found in the Qt framework, as well as its performance characteristics and optimization options.

In this chapter, we will discuss the following topics:

  • Introduction to networking: To get you started on data communication
  • Qt networking classes: An overview of what Qt Network has to offer
  • Improving network performance: To show you some useful techniques
  • Advanced networking themes: To give you more perspective

You do not need any previous networking knowledge to read this...
