商品描述

Systems performance analysis and tuning lead to a better end-user experience and lower costs, especially for cloud computing environments that charge by the OS instance. Systems Performance, 2nd Edition covers concepts, strategy, tools, and tuning for operating systems and applications, using Linux-based operating systems as the primary example.

World-renowned systems performance expert Brendan Gregg summarizes relevant operating system, hardware, and application theory to quickly get professionals up to speed even if they've never analyzed performance before, and to refresh and update advanced readers' knowledge. Gregg illuminates the latest tools and techniques, including extended BPF, 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:

  • Hardware, kernel, and application internals, and how they perform
  • Methodologies for rapid performance analysis of complex systems
  • Optimizing CPU, memory, file system, disk, and networking usage
  • Sophisticated profiling and tracing with perf, Ftrace, and BPF (BCC and bpftrace)
  • Performance challenges associated with cloud computing hypervisors
  • Benchmarking more effectively


Fully updated for current Linux operating systems and environments, Systems Performance, 2nd Edition addresses issues that apply to any computer system. The book will be a go-to reference for many years to come and recommended reading at many tech companies, like its predecessor first edition.

商品描述(中文翻譯)

系統性能分析和調優可以提升終端用戶體驗並降低成本,尤其對於按操作系統實例計費的雲計算環境尤為重要。《系統性能,第二版》涵蓋了操作系統和應用程序的概念、策略、工具和調優,以Linux為主要示例。

世界知名的系統性能專家Brendan Gregg摘要了相關的操作系統、硬件和應用程序理論,即使對性能分析沒有經驗的專業人士也能快速上手,同時也能更新進階讀者的知識。Gregg介紹了最新的工具和技術,包括擴展的BPF,展示如何在雲計算、Web和大型企業環境中充分利用系統。他涵蓋了以下關鍵主題:

- 硬件、內核和應用程序的內部運行和性能
- 快速分析複雜系統性能的方法論
- 優化CPU、內存、文件系統、磁盤和網絡使用
- 使用perf、Ftrace和BPF(BCC和bpftrace)進行高級分析和追蹤
- 雲計算虛擬化器帶來的性能挑戰
- 更有效的基準測試

《系統性能,第二版》完全更新了當前Linux操作系統和環境,涉及適用於任何計算機系統的問題。這本書將成為未來多年的參考書,並被許多科技公司推薦閱讀,就像它的前作第一版一樣。
