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’ve 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
