真長...看瞭好久。工程問題科學化典範。Brendan 在不瞭解 Redis 工作機製情況下,暴力破解齣 bgsave 造成的延遲問題也是炸天 diao。
評分好好學習
評分對於存儲和網絡都比較熟悉的童稚可以直奔最後一章,案例分析。精華在於dtrace腳本及其它各種統計工具的使用。
評分碼農和運維狗都應該拜讀一下
評分大師之作,不僅介紹瞭性能分析和排障的各種工具,更是總結瞭性能分析和排障的方法論,幫助我們不僅看到性能問題,更為我們指瞭一條追根溯源的路。
Brendan Gregg (San Francisco, CA area) is Lead Performance Engineer at Joyent, where he analyzes performance and scalability for small to large cloud computing environments, at any level of the software stack. He is primary author of DTrace and co-author of Solaris Performance and Tools (both from Prentice Hall); as well as numerous articles about systems performance. Previously performance lead and kernel engineer at Sun Microsystems, he has also consulted and trained IT professionals on performance optimization. He developed DTraceToolkit and ZFS L2ARC, and many of his DTrace scripts are shipped by default in Mac OS X and Oracle Solaris 11. His recent work has included performance visualizations.
The accelerating deployment of large-scale web, cloud, Big Data, and virtualized computing systems has introduced serious new challenges in performance optimization. Until now, however, little reliable, practical information has been available to IT professionals who are responsible for running these systems efficiently and cost-effectively.
Systems Performance: Enterprise and the Cloud is the solution. Internationally renowned performance optimization expert Brendan Gregg brings together state-of-the-art techniques and tools for analysis and tuning of large-scale web/cloud computing environments.
Gregg focuses on Linux/Unix/Solaris performance issues, while offering proven methodologies and discussing key issues that apply to all enterprise operating systems. Coverage includes:
Modern performance analysis and capacity planning, including key issues such as latency and dynamic tracing
New performance and reliability challenges associated with cloud computing
Methodology, concepts, terminology, tools, and metrics
Key tradeoffs, including problems of load vs. architecture
Tuning operating systems, CPUs, memory, file systems, disks, networks, and busses
Tuning virtualized systems
Programming language issues related to performance — including application profiling for C, C++, Java, and node.js
Benchmarking strategies and pitfalls, including custom microbenchmarking
相对来说,读起来累是比较次要的。 读到第 83 页读不下去了,82/83 页有一段是这样的: ...... 而是只添加一个系统调用:perf_event_open(),它会用 ioctl() 返回一个文件描述符。...... 在这种情况下,开发人员可以很容易地对参数 PERF_EVENT_IOC_ENABLE 做添加和修改。 找了...
評分《性能之巅:洞悉系统、企业与云计算》基于Linux 和Solaris系统阐述了适用于所有系统的性能理论和方法,Brendan Gregg 将业界普遍承认的性能方法、工具和指标收集于本书之中。阅读本书,你能洞悉系统运作的方式,学习到分析和提高系统与应用程序性能的方法,这些性能方法同样适...

評分第一次知道Brendan Gregg,是我还在Juniper的时候。插点花絮,关于Juniper,你可以百度下“程序员薪水最高的25家公司”,那就是因为这条新闻才打定了主意去的Juniper, 只能说,Juniper的HR们很优秀。 言归正传,我那会在Juniper主要是研究网络性能优化的一些东西,Juniper...
