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.

Building and Deploying Go Code

Once we have come up with a method to write performant Go code, we need to ship it, validate it, and continue iterating it. The first step of this process is to deploy the new Go code. Go's code is compiled into binaries, which allows for the modular deployment of new Go code as we iterate through code development. We can push this out to one or multiple places in order to test against different environments. Doing this will allow us to optimize our code to fully utilize the throughput that will be available to us in our system.

In this chapter, we will learn all about the Go build process. We'll look at how the Go compiler builds binaries, and we'll use this knowledge to build right-sized, optimized binaries for the platform at hand. We will cover the following topics:

  • Building Go binaries
  • Using go clean to remove object files
  • Using...
