Efficient C++: Performance Programming Techniques

Efficient C++: Performance Programming Techniques, Dov Bulka, David Mayhew, ISBN: 0201379503

The book title suggested to me that the book would follow the Effective C++ series format where advices are given in small items. This is not the case. This book has a more conservative format where topics are presented in chapters. This is not a problem per se but I just wanted to say it to potential readers that could have the same impression that I had by seeing the title. That being said, the topics covered are the usual areas where you can usually gain some performance such as temporaries, memory allocation and inlines. I cannot say that I have learned a lot of things because writing performant C++ code has been a topic of interest to me for a very long time.

The chapter about inlines is mixed bag of very good information and useless information. What I did appreciate less is that several pages are dedicated for describing what could be possible to do with inlines if very smart compilers were available. It was interesting to read but nothing applicable immediatly. Maybe this section is a wish list intended to be read by compiler implementers. However at the same time, it is the chapter that gave me the most new tricks that I did not already knew. This is the book that presents how to efficiently use inlines in the best way that I have seen in books.

Finally, if I abstract the fact that I did not learn a lot of new things, I must say that it is very well written. It is interesting to read. The authors give reference to actual cases from their work experience and this book would probably be very beneficial to read for someone that has never yet spent a lot of time doing code optimization.

Code Optimization: Effective Memory Usage

Code Optimization: Effective Memory Usage, Kris Kaspersky, ISBN: 1931769249

This book has been a revelation to me. Prior to read this book, all I knew was that memory access was expensive. This book will teach you how to organize your data in memory and how to access it to improve your program performance and most of the time without having to use assembly programming. It covers x86 memory organization and the interface between the processor and the memory and there is a whole chapter covering x86 processor cache memory. To me, the most shocking information contained in this book is a C implementation of memcpy() that outbeats VC++ implementation by 25%-30%!!!

This book is not for novices but if you are ready to change your perception forever of the x86 programming, this book is highly recommended!

I want you to find in this blog informations about C++ programming that I had a hard time to find in the first place on the web.
