ASP.NET Core 2 High Performance - Second Edition

By: James Singleton

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.

Caching


It is often said (originally by Phil Karlton) that caching is one of the hardest problems in computer science, along with naming things. This may well be an exaggeration, but caching is certainly difficult. It can also be very frustrating to debug if you are not methodical and precise in your approach.

Caching can apply at various different levels from the browser to the server using many diverse technologies. You rarely use just a single cache even if you don't realize it. Multiple caches don't always work well together, and it's vexing if you can't clear one.

We briefly touched upon caching in the previous chapter, and we'll go into much more detail in Chapter 9, Learning Caching and Message Queuing. However, as caching has an impact on network performance, we'll cover it here as well.

Browser

A lot of caching happens in the web browser, which is inconvenient because you don't have direct control over it (unless it's your browser). Asking users to clear their cache is unsatisfactory...
