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.

STL Algorithm Equivalents in Go

Many programmers coming from other high-performance programming languages, particularly C++, understand the concept of the Standard Templating Library (STL). This library provides common programming data structures and functions access to a generalized library in order to rapidly iterate and write performant code at scale. Go does not have a built-in STL. This chapter will focus on how to utilize some of the most common STL practices within Go. The STL has four commonly referenced components:

  • Algorithms
  • Containers
  • Functors
  • Iterators

Being familiar with these topics will help you to write Go code more quickly and effectively, utilizing commonly implemented and optimized patterns. In this chapter, we are going to learn the following:

  • How to use STL practices in Go
  • How to utilize standard programming algorithms with respect to Go
  • How containers...
