Systems Performance, Second Edition, covers concepts, strategy,
tools, and tuning for operating systems and applications, using
Linux-based operating systems as the primary example. A deep
understanding of these tools and techniques is critical for developers
today. Implementing the strategies described in this thoroughly revised
and updated edition can lead to a better end-user experience and lower
costs, especially for cloud computing environments that charge by the OS
instance.
Systems performance expert and best-selling author Brendan Gregg
summarizes relevant operating system, hardware, and application theory
to quickly get professionals up to speed even if they have never
analyzed performance before. Gregg then provides in-depth explanations
of the latest tools and techniques, including extended BPF, and shows
how to get the most out of cloud, web, and large-scale enterprise
systems. Key topics covered include
- 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
Featuring up-to-date coverage of Linux operating systems and
environments, Systems Performance, Second Edition, also addresses
issues that apply to any computer system. The book will be a go-to
reference for many years to come and, like the first edition, required
reading at leading tech companies.
