Overview of this book

The ASP.NET Core 2 framework is used to develop high-performance and cross-platform web applications. It is built on .NET Core 2 and includes significantly more framework APIs than version 1. This book addresses high-level performance improvement techniques. It starts by showing you how to locate and measure problems and then shows you how to solve some of the most common ones. Next, it shows you how to get started with ASP.NET Core 2 on Windows, Mac, Linux, and with Docker containers. The book illustrates what problems can occur as latency increases when deploying to a cloud infrastructure. It also shows you how to optimize C# code and choose the best data structures for the job. It covers new features in C# 6 and 7, along with parallel programming and distributed architectures. By the end of this book, you will be fixing latency issues and optimizing performance problems, but you will also know how this affects the complexity and maintenance of your application. Finally, we will explore a few highly advanced techniques for further optimization.

Linux

Linux is a hugely popular OS outside of the desktop market. Android (the mobile operating system acquired by Google) is based on it, and it runs on most of the world's smartphones. Sometimes it is the main desktop option, if using a computer with specialized hardware, such as the Raspberry Pi. Linux is very popular on embedded devices, in part because it is lightweight and usually much less demanding on resources than a typical Windows or macOS installation.

Linux is also the most popular operating system for web servers, which is what interests us most here. It could be argued that Linux is the most popular operating system on the planet, although many users won't interact with it directly.

Strictly speaking, Linux only refers to the kernel of the OS. The equivalent part of Windows would be the NT kernel. Many different distributions are built using the Linux...
