It is so fundamental that it could be called the zeroth-order performance metric.
In the context of computer performance analysis, time manifests itself in a multitude of metrics like service time, response time, round-trip time, memory latency, and mean time to failure, to name just a few. In view of this variety, it would seem fitting to open a book on performance analysis with a review of these various performance metrics.
Surprisingly, there seems to be no precedent for such a discussion in any of the readily available textbooks on computer performance analysis. It is about time someone provided a brief discourse about time, and that is what we offer in this chapter. Think about the times you have had to wait in line because other people wanted the same thing you did, and you get that sinking feeling so often associated with the phenomenon of queueing, the bane of modernity.

PDQ is an open-source performance analyzer based on the paradigm of queues. Stuff about computing…mostly Queues are ubiquitous in every computing environment as buffers, and since any application architecture can be represented as a circuit of queueing delays, PDQ is a natural fit for analyzing system performance.

Ciudad de Hueso: Cazadores de sombras 1 Spanish Edition? This book is about systematic, model-driven test processes in the context of UML. Written by the original members of this standardization group, this book shows you how to use UML to test complex software systems. The authors introduce UTP step-by-step, using a case study that illustrates how UTP can be used for test modeling and test specification. This book is the definitive reference for the only UML-based test specification language, written by the creators of that language.
It is supported by an Internet site that provides information on the latest tools and uses of the profile. A key Guerrilla concept is tactical planning whereby short-range planning questions and projects are brought up in team meetings such that management is compelled to know the answer, and therefore buys into capacity planning without recognizing it as such.
Once you have your "foot in the door", capacity planning methods can be refined in an iterative cycle of improvement called "The Wheel of Capacity Planning". Gunther's "Universal Law of Computational Scaling", which provides a highly cost-effective method for assessing application scalability. Readers learn how to use a domain model to make a complex development effort more focused and dynamic. A core of best practices and standard patterns provides a common language for the development team.
A shift in emphasis—refactoring not just the code but the model underlying the code—in combination with the frequent iterations of Agile development leads to deeper insight into domains and enhanced communication between domain expert and programmer. Domain-Driven Design then builds on this foundation, and addresses modeling and design for complex systems and larger organizations.
Specific topics covered include:. With this book in hand, object-oriented developers, system analysts, and designers will have the guidance they need to organize and focus their work, create rich and useful domain models, and leverage those models into quality, long-lasting software implementations. You will learn how to use tools and APIs to automate scalable distributed systems, whether it is for online services, machine-learning applications, or a cluster of Raspberry Pi computers. The algorithms in this book represent a body of knowledge developed over the last 50 years that has become indispensable, not just for professional programmers and computer science students but for any student with interests in science, mathematics, and engineering, not to mention students who use computation in the liberal arts.
The course offers more than video lecture segments that are integrated with the text, extensive online assessments, and the large-scale discussion forums that have proven so valuable.
Offered each fall and spring, this course regularly attracts tens of thousands of registrants. Robert Sedgewick and Kevin Wayne are developing a modern approach to disseminating knowledge that fully embraces technology, enabling people all around the world to discover new ways of learning and teaching. By integrating their textbook, online content, and MOOC, all at the state of the art, they have built a unique resource that greatly expands the breadth and depth of the educational experience.

Reiner Dumke. Initially, computer systems performance analyses were carried out primarily because of limited resources. Due to ever increasing functional complexity of computational systems and user requirements, performance engineering continues to play a major role in software development. This book assesses the state of the art in performance engineering.
Besides revised chapters drawn from two workshops on performance engineering held in , additional chapters were solicited in order to provide complete coverage of all relevant aspects. The first part is devoted to the relation between software engineering and performance engineering; the second part focuses on the use of models, measures, and tools; finally, case studies with regard to concrete technologies are presented. Researchers, professional software engineers, and advanced students interested in performance analysis will find this book an indispensable source of information and reference.
Guide to Advanced Empirical Software Engineering.
Forrest Shull. Empirical studies have become an important part of software engineering research and practice. Ten years ago, it was rare to see a conference or journal article about a software development tool or process that had empirical data to back up the claims.

Today, in contrast, it is becoming more and more common that software engineering conferences and journals are not only publishing, but eliciting, articles that describe a study or evaluation. Moreover, a very successful conference International Symposium on Empirical Software Engineering and Measurement , journal Empirical Software Engineering , and organization International Software Engineering Research Network have all evolved in the last 10 years that focus solely on this area.
While empirical software engineering has seen such substantial growth, there is not yet a reference book that describes advanced techniques for running studies and their application. This book aims to fill that gap. The chapters are written by some of the top international empirical software engineering researchers and focus on the practical knowledge necessary for conducting, reporting, and using empirical methods in software engineering. The book is intended to serve as a standard reference.
