Hands-On High Performance with Go

By: Bob Strecansky

Overview of this book

Go is an easy-to-write language that is popular among developers thanks to its features such as concurrency, portability, and ability to reduce complexity. This Golang book will teach you how to construct idiomatic Go code that is reusable and highly performant. Starting with an introduction to performance concepts, you’ll understand the ideology behind Go’s performance. You’ll then learn how to effectively implement Go data structures and algorithms along with exploring data manipulation and organization to write programs for scalable software. This book covers channels and goroutines for parallelism and concurrency to write high-performance code for distributed systems. As you advance, you’ll learn how to manage memory effectively. You’ll explore the compute unified device architecture (CUDA) application programming interface (API), use containers to build Go code, and work with the Go build cache for quicker compilation. You’ll also get to grips with profiling and tracing Go code for detecting bottlenecks in your system. Finally, you’ll evaluate clusters and job queues for performance optimization and monitor the application for performance regression. By the end of this Go programming book, you’ll be able to improve existing code and fulfill customer requirements by writing efficient programs.

Maintaining readability in Go

Readability is another core tenet of Go. Being able to quickly grok a new code base and understand some of its nuances is an important part of any programming language. As distributed systems continue to grow, with vendored libraries and APIs becoming more commonplace, being able to easily read the code that is included and be able to make sense of it is helpful for forward momentum. This also makes broken code easier to fix.

Having concrete data types, interfaces, packages, concurrency, functions, and methods has helped Go to continue moving forward. Readability is one of the most important parameters of being able to maintain a large code base over an extended period of time, and this is one of the most important things that sets Go apart from its competitors. The language was constructed with readability as a first class citizen.
