This chapter will focus on optimizing an application, discovering bottlenecks, and vendoring dependencies. These are some tips and tricks that can be used immediately by existing applications. Many of these recipes are necessary if you or your organization require fully reproducible builds. They're also useful when you want to benchmark an applications' performance. The final recipe focuses on increasing the speed of HTTP, however, it's always important to remember that the web world moves quickly, and it's important to refresh yourself on best practices. For example, if you require HTTP/2, it is now available using the built-in Go net/http package since version 1.6.

Overview of this book
Go (a.k.a. Golang) is a statically-typed programming language first developed at Google. It is derived from C with additional features such as garbage collection, type safety, dynamic-typing capabilities, additional built-in types, and a large standard library.
This book takes off where basic tutorials on the language leave off. You can immediately put into practice some of the more advanced concepts and libraries offered by the language while avoiding some of the common mistakes for new Go developers.
The book covers basic type and error handling. It explores applications that interact with users, such as websites, command-line tools, or via the file system. It demonstrates how to handle advanced topics such as parallelism, distributed systems, and performance tuning. Lastly, it finishes with reactive and serverless programming in Go.
