What do readers say?
Here are some excerpts from reviews about the book:
“This book is incredibly well-crafted…Ben’s style provides layers to these topics so the reader can choose how deep to go while still gaining valuable insights.” 5 stars – T. Segal
“It’s engaging, and reads like a technical memoirs of the lessons learned from the genesis of a very large scale .NET service. Readability is great, but the technical content is invaluable…. I personally felt that the chapter on GC alone is easily worth the price of the book and the time to read it….it’s an excellent resource to fully understand what you need to know about GC…. This book does a very good job and breaking down the myths of poor performing managed code, and the optimal strengths managed code has over native…. I gave this book 5 stars for several reasons. First, it delivers on the content and readability the book is selling. The price is also very generous for the content you’re getting.” 5 stars – I. Paradiso
“This is an awesome book–a must read for performance engineers of all levels, supported with tools, techniques, and statistics.” 5 stars – Bipin P.
“This is why this book stood out; the author used real-life examples to provide clear, concise explanations about the .Net framework. I would recommend this book to anyone who is weighing the benefits of managed-code vs unmanaged code.” 5 stars – Emit B.
“Concise and straight to the point…it caters to all levels of expertise.” 5 stars – L. Gomez
