Title: Lack of vision
Review: There is a lack of vision in this book as to what it wants to achieve. For a "101" book I was expecting to have a systematic approach to diagnosing and tuning system performance. Instead it wastes a lot of time on very general statements such as "choose the right balance", "find the bottleneck and then tune it" etc. I would expect that such things are obvious in fixing any problem.i.e. you understand the nature of the problems and then fix them.There is a start along the direction of using a systematic approach but the author doesn't follow through.
Is the review positive or negative?
