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


As covered in previous chapters, latency is the delay that occurs before an operation can complete, sometimes also known as lag. You may not be able to control the latency of the infrastructure that your software runs on, but you can write your application in such a way that it can cope with this latency in a graceful manner.

The two main types of latency that we will discuss here are network latency and disk latency. As the names suggest these are, respectively, the delay in performing an operation over the network and the delay to read from or write to a persistent storage medium. You will often deal with both at the same time, for example, a database (DB) query to a server on a remote virtual machine will require the following operations:

  • A network operation from web server to DB server

  • A network operation from DB server to remote disk on a Storage Area Network (SAN)

  • A disk operation to look up data on the physical drive


Although Solid State Drives (SSDs) have much lower latency...
