Folks who can optimize Linux performance in the enterprise are scarce -- and valuable. With this book, you can be one of them.
Optimizing Linux Performance shares Phillip Ezolt’s lessons from a decade of diagnosing Linux/UNIX performance. First, Ezolt demonstrates how to use Linux’s essential tools for measuring CPUs, memory, processes, disk I/O, and networking. Next, he takes on dozens of real-world issues. Is a process devouring too many CPU cycles? Is the kernel servicing too many interrupts? Is swap space a problem? Are any network devices operating near their limits?
Ezolt introduces a systematic methodology for identifying problems, baselining, goal setting, configuring applications, running performance tools, and analyzing results. You’ll put it to work in three chapter-length case studies, clearing bottlenecks in CPU-bound and latency-sensitive apps and diagnosing systemwide slowdowns. This is relentlessly practical, hands-on stuff, distilled for use by any experienced Linux admin. Bill Camarda, from the May 2005 Read Only
