The first comprehensive, expert guide for end-to-end Linux application optimization
Learn to choose the right toolsand use them together to solve real problems in real production environments
Superior application performance is more crucial than everand in today's complex production environments, it's tougher to ensure, too. If you use Linux, you have extraordinary advantages: complete source code access, plus an exceptional array of optimization tools. But the tools are scattered across the Internet. Many are poorly documented. And few experts know how to use them together to solve real problems. Now, one of those experts has written the definitive Linux tuning primer for every professional: Optimizing Linux® Performance.
Renowned Linux benchmarking specialist Phillip Ezolt introduces each of today's most important Linux optimization tools, showing how they fit into a proven methodology for perfecting overall application performance. Using realistic examples, Ezolt shows developers how to pinpoint exact lines of source code that are impacting performance. He teaches sysadmins and application developers how to rapidly drill down to specific bottlenecks, so they can implement solutions more quickly. You'll discover how to:
Identify bottlenecks even if you're not familiar with the underlying system
Find and choose the right performance tools for any problem
Recognize the meaning of the events you're measuring
Optimize system CPU, user CPU, memory, network I/O, and disk I/Oand understand their interrelationships
Fix CPU-bound, latency-sensitive, and I/O-bound applications, through case studies you can easily adapt to your own environment
Install and use oprofile, the advanced systemwide profiler for Linux systems
If you're new to tuning, Ezolt gives you a clear and practical introduction to all the principles and strategies you'll need. If you're migrating to Linux, you'll quickly master Linux equivalents to the tools and techniques you already know. Whatever your background or environment, this book can help you improve the performance of all your Linux applicationsincreasingbusiness value and user satisfaction at the same time.

Customer Reviews & Comments
[Review: long] First about the title: The title should have been just "A Hands-On Guide to Linux(R) Performance Tools". That would have been less missleading and most readers could have appreciated the debugging scenarios at the end of the book more. O.K now about the book itself: I am currently a system administrator in a medium sized company (ca. 200 employees) I am using different flavours of Linux since 5+ years (Debian, Mandrake, Suse, Redhat etc). Every now and then I found several man pages sometimes hard to comprehend. Most man pages do describe available options on their own but - unfortunately - they fail to deliver the big picture, including f.e. practical samples of how to use those options in real life scenarios and how to evaluate (read) the output given to the screen (or a file). This is exactly where Ezolt comes in with the "Hands-on Guide" and ease the pain in a fantastic way. Whats makes this book so indispensible is that it describes the below list of tools in a way that demystifies many of the command line options and the screen clutter. The book immediately became my best friend. The book is with 350p quite compact (keep in mind the many tools described below) and that allows you to take it with you onsite, while not being to heavy. To really maximise the usage of the book I suggest to use little post-it like notes, so that you can refer to them, when you are onsite and forgot the one or the other trick. My post-it notes loose regularly the writing from the many tear (usage). ;-) Note that many of the tools below are described 2 times or more within the book, depending on their usage f.e. as CPU or Memory based investigation tool. The book is somehow different from what I expected, but keep in mind that one book can seldom tackle all issues and I believe Ezolt has striked a very good balance here. Ezolt is describing many scenarios that probably most system admin came accross, but didnt know yet how to handle them. Ezolt now gave them the tools to finally put them to good use in a wide area. I give Ezolt both thumbs up alone for the fact that it is the first book out there that tackled that man page issue quite nicely and "translated" those man pages including the refering command line interfaces in a for me readable format. Well done !! List of (mostly command line) tools described in the book (39): For CPU + based troubleshooting (13): vmstat top procinfo gsm mpstat sar oprofile time strace ltrace ps ld.so gprof For Memory based troubleshooting (8): free slabtop memprof valgrind kcachegrind ipcs iostat lsof For Network based troubleshooting (8): miitool ethtool ifconfig ip gkrellm iptraf netstat etherape Utility tools (10): bash tee script watch gnumeric ldd objdump (f)grep gdb gcc
