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.

Memory Management in Go

Memory management is paramount to system performance. Being able to utilize a computer's memory footprint to the fullest allows you to keep highly functioning programs in memory so that you don't often have to take the large performance hit of swapping to disk. Being able to manage memory effectively is a core tenet of writing performant Go code. In this chapter, we will learn about the following topics:

  • Computer memory
  • How memory is allocated
  • How Go utilizes memory effectively
  • How objects are allocated in memory
  • Strategies for computing devices with limited memory

Understanding how memory is utilized can help you learn to utilize memory effectively in your programs. Memory is one of the fastest places in the computer to store and manipulate data, so being able to manage it performantly will have a lasting impact on your code quality.
