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.
Table of Contents (20 chapters)
Section 1: Learning about Performance in Go
Section 2: Applying Performance Concepts in Go
Section 3: Deploying, Monitoring, and Iterating on Go Programs with Performance in Mind


In this chapter, we discussed the different methodologies of comparing code quality across versions:

  • Utilizing the Go Prometheus exporter
  • APM tools
  • SLIs and SLOs
  • Utilizing logging

Utilizing all of these techniques can help you to determine where your application isn't performing as it is expected to. Knowing these things can help you to iterate rapidly and produce the best software that you can.

Throughout the course of this book, you've learned about application performance and how it pertains to Go. I hope this book will help you to think about web performance while you are writing applications. Always keep performance in the forefront of your mind. Everyone enjoys performant applications, and hopefully this book will help you do your part as a developer in making them.
