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.

Measuring Performance Bottlenecks

Profiling and measurement

We started this book by highlighting the importance of measurement and profiling by covering some simple techniques in Chapter 2, Measuring Performance Bottlenecks . We continued this theme throughout, and we'll end the book on it as well because it's impossible to overstate how important measuring and analyzing reliable evidence is.

Previously, we covered using Glimpse to provide insights into the running of your web application. We also demonstrated the Visual Studio diagnostics tools and the Application Insights Software Development Kit (SDK). There's another tool that's worth mentioning and that's the Prefix profiler, which you can get at .

Prefix is a free web-based ASP.NET profiler that supports ASP.NET Core. However, it doesn't support .NET Core yet (although this is planned), so you'll need to run ASP.NET Core on .NET Framework 4.6 for now. There's a live demo on their website (at ) if you want to quickly check it out and it looks...
