Key benefits

Build efficient and concurrent applications in Qt to create cross-platform applications

Identify performance bottlenecks and apply the correct algorithm to improve application performance

Delve into parallel programming and memory management to optimize your code

Description

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

Simply a great book on performance!

Subscriber review

Roman Apr 29, 2019

The book is virtually the only book book on Qt performance at this point in time, and it does its job exceptionally well, It gives you an insight on existing tools and how to use them, on existing techniques and how to apply them, and on the various aspects of performance from a C++ perspective, as you can't really talk about Qt performance without talking about C++ performance. I consider myself a seasoned Qt and C++ developer, but I had a lot to learn from this book, and I would definitely recommend it to anyone dealing with Qt, the book really covers a lot.Another thing, which is not less important, is that the book is written really well, it is easy to read, and to understand.That being said - I noticed a few typos (not many though), the book is more Windows oriented (but many important Linux specific topics are also in the book), and I skipped almost everything related to QML, but this is not enough to detract a star from the ratings, so here we go.Very highly recommended.
