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.

Extended capabilities with upstream pprof

If we want to be able to use additional functionality by default, we can use the upstream pprof binary in order to extend the views we have with our profiles:

  1. We can retrieve this with an invocation of go get The pprof tool has a couple different invocation methods. We can use the report generation method to generate a file in the requested format (currently supported are the .dot, .svg, .web, .png, .jpg, .gif, and .pdf formats). We can also use the interactive terminal format in a similar way to what we did in the previous sections about CPU and memory profiling. The last and most commonly used method is using the HTTP server. This method involves hosting an HTTP server that includes much of the pertinent output in an easily digestible format.
  1. Once we have retrieved the binary via go get, we can invoke it with...
