C++ High Performance: Master the art of optimizing the functioning of your C++ code, 2nd Edition

Written at the right level of depth (not for beginners). Emphasizes modern idioms (C++20). Balanced, thoughtful advice. The comparative language analysis aids in compensation and helps weigh tradeoffs.

I normally like to wait until I have finished reading a book before giving a rating. But I must say that so far, it's very good. The authors do a good job explaining things that other authors make more complicated than they should be. When I finish the book and things change, I'll update my review. But currently, five stars.

This book is good in going through modern C++ features, but it is for beginners, spent a lot pages to explain basics and not into depth

Was hesitant to buy Kindle version because I’ve found that source code formatting is often less than optimal. Preview provided on website didn’t look bad. Found myself pondering for a second what source code was saying. Suddenly realized that names were hyphenated. It’s a shame author’s hard work spoiled. Frustrated that technical books are much more expensive, even in Kindle format, but not getting additional value for the inflated price tag.

Great book for anyone looking to up their c++ knowledge and increase efficiency across the board. If your very new to c++ it may not be as easy to read but anyone could ultimately gain from the info within these pages.

If i could only keep one of my c++ books it would be this one. it covers a lot of ground and shows how to use tools in the modern language additions, all while being reasonably concise.

A very practical book which I enjoyed reading cover to cover.

This is a great book, like the other reviewers have said. 5-star content, no doubt. The publisher, Packt, doesn't do justice to this book, with their sloppy work. 1. Poor paper quality 2. Sections and subsections are hardly identifiable! They don's use numerical section titles like 1, 1.1, 1.1.1. The use different font size to differentiate sections and subsections. It is VERY easy to lose track and that is very annoying 3. The book is > 500 pages (intimidating! I always prefer a technical book to be around 300 pages). With a proper formatting, and typesetting, the book can be easily reduced to 350 pages. I don't understand why the authors choose Packt as the publisher. They are not known for high-quality books and their reputation does not match the book - there are better ones out there. P.S. In the Forward, it is said "Victor and Bjorn are brilliant and experienced developers with a remarkable pedigree" - what in the world does "with a remarkable pedigree" mean? Updates - read the book, but take what it says with a pinch of salt and be careful of the typos and inaccuracies. For example, Page 144, it gives totally wrong interpretation of std::ranges:upper_bound.

Fabulous book

The book is well written, easy to read, and full of code snippets that help understand its content. It covers many topics: the first half is about essential modern C++ techniques, algorithms, and data structures, while the second half covers memory management, compile-time programming, multithreading, and coroutines. Covering so many topics in a 500 pages book has the advantage of giving a good general idea of what optimizing code means, how to do so in C++20, and what to be aware of. The downside is that the surface is barely scratched: there are books on algorithms or concurrent programming alone that are longer than this entire book. I was mostly interested in the second half of the book, which has a chapter on memory management that I really wanted to read. I can't say that thanks to this book I now have an in-depth knowledge of how the OS manages memory, but I still learned a lot and I am glad I bought it. A special mention goes to the compile-time programming and multithreading chapters, they are very well done. Finally, a small negative note: the coroutines' chapters, especially the one on asynchronous programming, are quite cryptic compared to the rest of the book. Coroutines are not fully supported in the standard library yet, so even their basic usage is very complex, and at the end of the aforementioned chapters, I felt like I didn't learn that much. I would have preferred a greater focus on other topics, leaving coroutines for a future edition, when they'll be properly supported.

beaucoup d'explications permettant de s'améliorer. Pour un public averti

Well written, practical examples, few repetitions and to the point. I have enjoyed the writing style, it is easy to understand and adapt to your own needs.

Sehr empfehlenswert. Konnte einiges an Wissen aus dem Buch beziehen. Der Autor hat nicht nur theoretisches sondern auch praktisches know how und bringt es auch gut rüber.
