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

The Performance of Open Source Applications, which was edited by Travish Armstrong (available on http://aosabook.org, 2013), contains a chapter on optimizations that are used in the pugixml library. The Optimized C++ book by Kurt Guntheroth (2013) has a short chapter on the performance of std::iostream.

There are several good books on operating systems, but the most comprehensive when it comes to Windows is the book Windows Internals, Part 1: System architecture, processes, threads, memory management, and more by Pavel Yosifovich et al., Microsoft Press (seventh Edition, 2017). But be forewarned, it's quite a tome!
