How to Improve Java Performance and Scalability with a Quantitative Approach
Java is one of the most popular programming languages for developing software applications that require high performance and scalability. However, achieving these goals is not always easy, as Java developers need to deal with various challenges such as concurrency, memory management, garbage collection, and distributed systems. How can Java developers measure and improve the performance and scalability of their applications in a systematic and rigorous way
One possible answer is to use a quantitative approach based on software performance engineering (SPE) principles and techniques. SPE is a discipline that applies mathematical models and methods to analyze and predict the performance and scalability of software systems under different scenarios and workloads. SPE can help Java developers to identify and eliminate performance bottleneecs, optimize resource utilization, design scalable architectures, and evaluate trade-offs among different design alternatives.
A comprehensive and practical guide to applying SPE to Java applications is the book Java Performance and Scalability: A Quantitative Approach by Henry H. Liu [^1^]. This book covers the fundamental concepts and methods of SPE, such as workload characterization, performance metrics, queuing theory, operational analysis, simulation, and experimentation. It also provides detailed examples and case studies of applying SPE to various Java applications, such as web servers, database servers, enterprise applications, cloud computing, big data processing, and machine learning.
The book is divided into 12 chapters that cover the following topics:
Chapter 1: Introduction to software performance engineering
Chapter 2: Workload modeling and characterization
Chapter 3: Performance metrics and measurements
Chapter 4: Queuing theory and operational analysis
Chapter 5: Simulation modeling and analysis
Chapter 6: Experimental design and analysis
Chapter 7: Java performance fundamentals
Chapter 8: Java concurrency and synchronization
Chapter 9: Java memory management and garbage collection
Chapter 10: Java distributed systems
Chapter 11: Java web servers
Chapter 12: Java enterprise applications
The book is intended for Java developers who want to learn how to apply SPE to their projects, as well as for students and researchers who are interested in the field of software performance engineering. The book assumes some basic knowledge of Java programming, data structures, algorithms, statistics, and probability. The book also provides downloadable code examples and datasets for readers to practice and experiment with.
