Is your system running slower than you'd like? In today's cloud-driven world, performance issues aren't just frustrating—they're expensive. Every millisecond of delay translates to lost revenue, poor user experience, and wasted resources. Systems Performance, 2nd Edition is your comprehensive solution to these challenges, offering practical strategies that work in real-world environments.
Modern computing environments have made performance analysis both more critical and more complex. With cloud services charging by the instance and users expecting instant responses, understanding how your systems truly perform isn't optional—it's essential for maintaining competitive advantage and controlling costs. This book bridges the gap between theory and practice, showing you exactly where to look and what to look for when your systems aren't performing as expected.
Brendan Gregg, a world-renowned systems performance expert, distills complex concepts into actionable strategies that anyone can implement. Whether you're new to performance analysis or refreshing your knowledge, this book covers everything from hardware internals to application-level optimization. The latest tools and techniques, including extended BPF, are explained with clear examples that make advanced concepts accessible.
Discover how to use powerful tools like perf, Ftrace, and BPF (BCC and bpftrace) to uncover hidden bottlenecks in your systems. Learn to optimize CPU usage, memory allocation, file systems, disk performance, and networking—all with specific, actionable guidance. The book addresses modern challenges like cloud hypervisor performance and provides effective benchmarking methodologies that give you accurate, meaningful data.
This isn't just theory—it's a practical guide that has been recommended by tech companies worldwide. You'll learn how to apply these techniques in cloud environments, web services, and large-scale enterprise systems. The comprehensive coverage ensures you'll be able to troubleshoot performance issues regardless of your specific environment, making this an indispensable reference for years to come.
