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

Questions

As always, here are some questions so that you can test your understanding of the topics in this chapter:

  1. When would you deem a simple linear search to be a justifiable choice?
  2. How many items do you think can be shown without problems in a standard Qt's model-view setup?
  3. What could be meant with the Tower of Babel performance anti-pattern?
  4. Your program is suffering from a performance problem. How would you try to solve it?
  5. You have far too many items in a view—what can you do about this?
  6. How is it possible to avoid performance fails in your project?
  7. What seems to be the number one reason for performance fails?
  8. What about the do it later performance culture and performance fails?
