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.
