High Performance Programming with Qt 5: Cross-Platform Application Development

This book is for Qt developers seeking to create high-performance applications for desktop and embedded devices. It requires programming experience with C++. The table of contents includes sections on understanding performant programs, profiling to find bottlenecks, diving into C++ and performance using data structures and algorithms efficiently, a guide to concurrency and multithreading, overcoming performance failures, understanding I/O performance and related problems, optimizing graphical performance, optimizing network performance, Qt performance on embedded and mobile platforms, and testing and deploying Qt applications.

With this book, you will learn classic performance best practices and understand modern hardware architecture and its impact on performance. You will also gain expertise in implementing tools and procedures used in performance optimization, as well as Qt-specific work techniques for graphical user interface (GUI) and platform programming. Furthermore, you will discover how to make Transmission Control Protocol (TCP) and Hypertext Transfer Protocol (HTTP) performant using the relevant Qt classes. Additionally, the improvements in Qt 5.9 and upcoming versions are explored, along with Qt's graphic engine architecture, strengths, and weaknesses.

By delving into parallel programming and memory management, this book equips you to optimize your code, identify performance bottlenecks, and refine your applications. To achieve this, you will master general computer performance best practices and tools to identify the reasons behind low performance. Moreover, you will gain expertise in techniques such as memory management and design guidelines to improve application performance. This comprehensive guide prepares you to tackle hands-on experience of Qt's most exciting application fields, including mobile and embedded development domains.

By the end of this book, you will be capable of building efficient, concurrent, and performance-oriented Qt applications for desktop and embedded devices. Whether you are targeting performance problems, or simply striving to make your applications more efficient, this book provides the essential knowledge to achieve those goals.
