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 Go binaries

In Chapter 10, Compile Time Evaluations in Go, we discussed some Go build optimizations that can potentially help optimize our build strategy. Go's build system has quite a few options that can help the system operator add additional parameterization to their build strategy.

The Go tool has many different methodologies for building our source code. Let's investigate top-level understandings of each, and then we will discuss each package in more depth. Knowing the key differences between these commands may help you to understand how they interplay with one another and choose the right tool for the job. Let's have a look at them:

  • go build: Builds a binary for your project, compiling packages and dependencies
  • go clean: Removes object and cached files from package source directories
  • go get: Downloads and installs packages and their dependencies...
