This IBM® Redbooks® publication focuses on gathering the correct technical information, and laying out simple guidance for optimizing code performance on IBM POWER8® processor-based systems that run the IBM AIX®, IBM i, or Linux operating systems. There is straightforward performance optimization that can be performed with a minimum of effort and without extensive previous experience or in-depth knowledge. The POWER8 processor contains many new and important performance features, such as support for eight hardware threads in each core and support for transactional memory. The POWER8 processor is a strict superset of the IBM POWER7+TM processor, and so all of the performance features of the POWER7+ processor, such as multiple page sizes, also appear in the POWER8 processor. Much of the technical information and guidance for optimizing performance on POWER8 processors that is presented in this guide also applies to POWER7+ and earlier processors, except where the guide explicitly indicates that a feature is new in the POWER8 processor. This guide strives to focus on optimizations that tend to be positive across a broad set of IBM POWER® processor chips and systems. Specific guidance is given for the POWER8 processor; however, the general guidance is applicable to the IBM POWER7+, IBM POWER7®, IBM POWER6®, IBM POWER5, and even to earlier processors. This guide is directed at personnel who are responsible for performing migration and implementation activities on POWER8 processor-based systems. This includes system administrators, system architects, network administrators, information architects, and database administrators (DBAs).

Get well-versed with ready-to-use techniques for creating high-performance queries and applications Key Features • Speed up queries and dramatically improve application performance by both understanding query engine internals and practical query optimization • Understand how the query optimizer works • Learn about intelligent query processing and what is new in SQL Server 2022 Book Description SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications. This book starts by describing the inner workings of the query optimizer, and will enable you to use this knowledge to write better queries and provide the query engine with all the information it needs to produce efficient execution plans. As you progress, you'll get practical query optimization tips for troubleshooting underperforming queries. The book will also guide you through intelligent query processing and what is new in SQL Server 2022. Query performance topics such as the Query Store, In-Memory OLTP and columnstore indexes are covered as well. By the end of this book, you'll be able to get the best possible performance for your queries and applications. What you will learn • Troubleshoot queries using methods including extended events, SQL Trace, and dynamic management views • Understand how the execution engine and query operators work • Speed up queries and improve app performance by creating the right indexes • Detect and fix cardinality estimation errors by examining query optimizer statistics • Monitor and promote both plan caching and plan reuse to improve app performance • Troubleshoot and improve query performance by using the Query Store • Improve the performance of data warehouse queries by using columnstore indexes • Handle query processor limitations with hints and other methods Who this book is for This book is for SQL Server developers who are struggling with slow query execution, database administrators who are tasked with troubleshooting slow application performance, and database architects who design SQL Server databases in support of line-of-business and data warehousing applications.

This book sets out to provide the theoretical foundations that will enable radio network planners to plan model and optimize radio networks using state-of-the-art findings from around the globe. It adopts a logical approach, beginning with the background to the present status of UMTS radio network technology, before devoting equal coverage to planning, modelling and optimization issues. All key planning areas are covered, including the technical and legal implications of network infrastructure sharing, hierarchical cell structure (HCS) deployment, ultra-high-site deployment and the benefits and limitations of using computer-aided design (CAD) software. Theoretical models for UMTS technology are explained as generic system models, stand-alone services and mixed services. Business modelling theory and methods are put forward, taking in propagation calculations, link-level, UMTS static and UMTS dynamic simulations. The challenges and goals of the automated optimization process are explored in depth using cutting-edge cost function and optimization algorithms. This theory-based resource containing prolific illustrative case studies explains the reasons for UMTS radio networks performance issues and how to use this foundational knowledge to model, plan and optimize present and future systems.

Performance optimization is a fundamental discipline in modern software development, directly influencing application speed, resource utilization, and the quality of user experience. This book offers a clear and practical exploration of performance optimization, introducing the essential principles, metrics, and methodologies necessary for writing efficient, scalable code. Readers are guided step by step through critical concepts such as execution time, algorithmic complexity, memory management, and input/output efficiency. Structured for clarity and depth, the book systematically examines the impact of data structures, algorithm design, and hardware considerations—including concurrency and parallelism—on program performance. Through real-world examples and actionable techniques, it addresses common pitfalls and provides effective strategies for measuring, analyzing, and improving the responsiveness and efficiency of software systems. Special chapters explore performance trade-offs in energy-constrained environments, the use of compilers and build tools, and balancing optimization with security requirements. This book is intended for students, working programmers, and technical professionals who seek to enhance their understanding of software efficiency. With an emphasis on both foundational concepts and practical application, it equips readers to diagnose performance bottlenecks, apply targeted optimizations, and maintain high standards of software quality throughout the development lifecycle. Whether read sequentially or used as a reference, it provides the essential knowledge required to develop high-performance, maintainable software across a broad range of computing environments.
