The Whole Information to Optimizing Techniques Performance


Written through the winner of the 2013 LISA Award for Remarkable Success in Device Administration

Large-scale Undertaking, cloud, and virtualized computing Techniques have presented critical Efficiency demanding situations. Now, the world over well known Efficiency skilled Brendan Gregg has introduced in combination confirmed methodologies, gear, and metrics for inspecting and tuning even probably the most advanced environments. Techniques Efficiency: Undertaking and the Cloud focuses on Linux® and Unix® Efficiency, even as illuminating Efficiency problems which might be related to all running Techniques. You’ll acquire deep perception into how Techniques paintings and carry out, and be informed methodologies for inspecting and making improvements to Device and alertness Efficiency. Gregg items examples from naked-steel Techniques and virtualized cloud tenants working Linux-based totally Ubuntu®, Fedora®, CentOS, and the illumos-based totally Joyent® SmartOS™ and OmniTI OmniOS®. He systematically covers Brand new Techniques Efficiency, together with the “conventional” research of CPUs, Reminiscence, disks, and networks, and new areas together with cloud computing and dynamic tracing. This e-book additionally is helping you determine and connect the “unknown unknowns” of advanced Efficiency: bottlenecks that emerge from components and interactions you weren’t conscious about. The textual content concludes with an in depth case observe, appearing how an actual cloud purchaser factor was once analyzed from begin to end.


Coverage includes

• Brand new Efficiency research and tuning: terminology, ideas, fashions, strategies, and techniques

• Dynamic tracing ways and gear, together with examples of DTrace, SystemTap, and perf

• Kernel internals: uncovering what the OS is doing

• The use of Device observability gear, interfaces, and frameworks

• Figuring out and tracking software performance

• Optimizing CPUs: processors, cores, hardware threads, caches, interconnects, and kernel scheduling

• Reminiscence optimization: digital Reminiscence, paging, swapping, Reminiscence architectures, busses, deal with areas, and allocators

• Record Device I/O, together with caching

• Garage units/controllers, disk I/O workloads, RAID, and kernel I/O

• Community-comparable Efficiency problems: protocols, sockets, interfaces, and bodily connections

• Efficiency implications of OS and hardware-based totally virtualization, and new problems encountered with cloud computing

• Benchmarking: getting correct effects and warding off commonplace mistakes


This Information is integral for someone who operates Undertaking or cloud environments: Device, Community, database, and internet admins; builders; and different pros. For college kids and others new to optimization, it additionally supplies workouts reflecting Gregg’s intensive educational enjoy.
