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.

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.
