Mastering High Performance with Kotlin: Understanding how to use Kotlin features with minimal overhead

Find out how to write Kotlin code without overhead and how to use different profiling tools and bytecode viewer to inspect expressions of Kotlin language.

Key Features

• Learn memory optimization, concurrency, multi-threading, scaling, and caching techniques to achieve high performance.
• Apply modern Kotlin features to speed up processing and implement highly efficient and reliable codes.
• Learn how to prevent unnecessary overhead and use profiling tools to detect performance issues.

Book Description

The ease with which we write applications has been increasing, but with it comes the need to address their performance. A balancing act between easily implementing complex applications and keeping their performance optimal is a present-day need. In this book, we explore how to achieve this crucial balance while developing and deploying applications with Kotlin. This book will help you learn how to use profiling tools to detect performance issues that affect user experience. You will also discover bytecode, which is generated to overcome performance bottlenecks.

The book starts by analyzing various Kotlin specifications to identify those potentially affecting performance adversely. Then, we move on to monitor techniques that enable us to identify performance bottlenecks and optimize performance metrics. Next, we look at techniques that help us achieve high performance: memory optimization, concurrency, multi-threading, scaling, and caching. We also look at fault tolerance solutions and the importance of logging. We’ll also cover best practices of Kotlin programming that will help you improve the quality of your codebase. By the end of the book, you will have gained insight into various techniques and solutions that will help create high-performance applications in the Kotlin environment.
