Systems Performance

Simply the most use performance engineering book that I own. I already had the first edition and had to buy this second edition. Its full of practical, real world advice for tuning modern Linux systems. It's readable, comprehensive and authoratitive.

I have an O'Reilly subscription so technically didn't need to buy this, but it's a quality book filled with fantastic insights, I highly recommend it to anyone interested in systems performance.

Very good book written by someone that has a big knowledge in Performance.

You cannot possibly overestimate importance of having such a book on the table of any serious Linux admin. A wealth of knowledge, and very systematic too.

I just finished reading the book. Read about 85% of the content from cover to cover. I didn't know that there were these kinds of tools and methods available for investigating compute systems and performance. Absolutely critical book to have if you have to spend time analyzing overall performance of compute systems in almost any capacity. The focus is on compute systems with operating systems. If you want advice on how to write optimized assembly for integrated controlers/PLCs or re-organize your C/C++ code to optimize L1/L2 caching accesses etc., you might find the book of limited value but there are still relevant bits in there about benchmarking and other concerns. I am the target audience for this book; my work is on a mix of servers/workstations/cloud compute for simulation and tools that make heavy use of compute power. I am lucky enough to be in on the whole cycle and get hands-on from requirements gathering and design stage to decommissioning and repurposing hardware. This book is already paying dividends in my thought process and approaches.
