Systems Performance, 2/e (Bestseller)

Systems Performance, 2nd Edition covers concepts, strategy, tools and tuning for Unix operating systems, with a focus on those that are Linux- and Solaris-based.

World-renowned system performance expert Brendan Gregg summarizes relevant operating system theory to quickly get students up to speed even if they’ve never optimized operating systems before, and to refresh and update advanced readers’ knowledge. Next, Gregg illuminates the latest tools and techniques, including dynamic tracing using DTrace and SystemTap, showing how to get the most out of your systems in cloud, web, and large-scale enterprise environments. He covers these and other key topics:

• Performance analysis and capacity planning
• Latency as a key theme for analysis
• New performance challenges associated with cloud computing
• Optimizing CPU, memory, file system, disk, and networking usage
• Sophisticated dynamic tracing with perf, ftrace, and BPF
• Benchmarking more effectively

Fully updated for current Linux/Unix operating systems and environments, Systems Performance, 2nd Edition addresses issues that apply across multiple distributions and are likely to remain crucial for many years to come.
