ASP.NET Core 1.0 High Performance

By: James Singleton, Pawan Awasthi

Overview of this book

ASP.NET Core is the new, open source, and cross-platform, web-application framework from Microsoft. It's a stripped down version of ASP.NET that's lightweight and fast. This book will show you how to make your web apps deliver high performance when using it. We'll address many performance improvement techniques from both a general web standpoint and from a C#, ASP.NET Core, and .NET Core perspective. This includes delving into the latest frameworks and demonstrating software design patterns that improve performance. We will highlight common performance pitfalls, which can often occur unnoticed on developer workstations, along with strategies to detect and resolve these issues early. By understanding and addressing challenges upfront, you can avoid nasty surprises when it comes to deployment time. We will introduce performance improvements along with the trade-offs that they entail. We will strike a balance between premature optimization and inefficient code by taking a scientific- and evidence-based approach. We'll remain pragmatic by focusing on the big problems. By reading this book, you'll learn what problems can occur when web applications are deployed at scale and know how to avoid or mitigate these issues. You'll gain experience of how to write high-performance applications without having to learn about issues the hard way. You'll see what's new in ASP.NET Core, why it's been rebuilt from the ground up, and what this means for performance. You will understand how you can now develop on and deploy to Windows, Mac OS X, and Linux using cross-platform tools, such as Visual Studio Code.

While we're on the subject of static assets, we should briefly mention image optimization. We'll cover this in much more detail in the next chapter, but it's worth highlighting some common problems here. As you have very little control over network conditions between your infrastructure and the user, low throughput may be a problem in addition to high latency.

Web applications heavily use images, especially on landing pages or home pages, where they might form a fullscreen background. It is regrettably common to see a raw photo from a camera simply dropped straight in. Images from cameras are typically many megabytes in size, far too big for a web page.

You can test whether there are problems on a web page using a tool, such as Google's PageSpeed Insights. Visit , enter a URL, and click on ANALYZE to view the results. Google use this information as part of their search engine ranking, so you would do well to take its advice...
