The Complete Guide to Optimizing Systems Performance Written by the winner of the 2013 LISA Award for Outstanding Achievement in System Administration Large-scale enterprise, cloud, and virtualized computing systems have introduced serious performance challenges. Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Systems Performance: Enterprise and the Cloud focuses on Linux(R) and Unix(R) performance, while illuminating performance issues that are relevant to all operating systems. You'll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare-metal systems and virtualized cloud tenants running Linux-based Ubuntu(R), Fedora(R), CentOS, and the illumos-based Joyent(R) SmartOS(TM) and OmniTI OmniOS(R). He systematically covers modern systems performance, including the "traditional" analysis of CPUs, memory, disks, and networks, and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the "unknown unknowns" of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish. Coverage includes - Modern performance analysis and tuning: terminology, concepts, models, methods, and techniques - Dynamic tracing techniques and tools, including examples of DTrace, SystemTap, and perf - Kernel internals: uncovering what the OS is doing - Using system observability tools, interfaces, and frameworks - Understanding and monitoring application performance - Optimizing CPUs: processors, cores, hardware threads, caches, interconnects, and kernel scheduling - Memory optimization: virtual memory, paging, swapping, memory architectures, busses, address spaces, and allocators - File system I/O, including caching - Storage devices/controllers, disk I/O workloads, RAID, and kernel I/O - Network-related performance issues: protocols, sockets, interfaces, and physical connections - Performance implications of OS and hardware-based virtualization, and new issues encountered with cloud computing - Benchmarking: getting accurate results and avoiding common mistakes This guide is indispensable for anyone who operates enterprise or cloud environments: system, network, database, and web admins; developers; and other professionals. For students and others new to optimization, it also provides exercises reflecting Gregg's extensive instructional experience.

The Complete Guide to Human Resources and the Law offers fast, dependable, plain English legal guidance for HR-related situations from ADA accommodation, diversity training, and privacy issues to hiring and termination, employee benefit plans, compensation, and recordkeeping. It brings you the most up-to-date information as well as practical tips and checklists in a well-organized, easy-to-use resource. The 2019 Edition provides new and expanded coverage of issues such as: The Supreme Court held in March 2016 that to prove damages in an Fair Labor Standards Act (FLSA) donning/doffing class action, an expert witness' testimony could be admitted Tyson Foods, Inc. v. Bouaphakeo, 136 S. Ct. 1036 (2016). Executive Order 13706, signed on Labor Day 2015, takes effect in 2017. It requires federal contractors to allow employees to accrue at least one hour of paid sick leave for every 30 hours they work, and unused sick leave can be carried over from year to year. Mid-2016 DOL regulations make millions more white-collar employees eligible for overtime pay, by greatly increasing the salary threshold for the white-collar exemption. Updates on the PATH Act (Protecting Americans From Tax Hikes; Pub. L. No. 114-113. The DOL published the "fiduciary rule" in final form in April 2016, with full compliance scheduled for January 1, 2018. The rule makes it clear that brokers who are paid to offer guidance on retirement accounts and Individual Retirement Arrangements (IRAs) are fiduciaries. In early 2016, the Equal Employment Opportunity Commission (EEOC) announced it would allow charging parties to request copies of the employer's position statement in response to the charge. The Supreme Court ruled that, in constructive discharge timing requirements run from the date the employee gives notice of his or her resignation--not the effective date of the resignation. Certiorari was granted to determine if the Federal Arbitration Act (FAA) preempts consideration of severing provisions for unconscionability.
