ASP.NET Core 1.0 High Performance

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.

Chapter 5.  Optimizing I/O Performance

This chapter addresses issues that often occur when you take your functionally tested application and split it up into parts for deployment. Your web servers host the frontend code, your database is somewhere else in the data center, you may have a Storage Area Network (SAN) for centralized files, an app server for APIs, and the virtual disks are all on different machines as well.

These changes add significant latency to many common operations and your application now becomes super slow, probably because it's too chatty over the network. In this chapter, you will learn how to fix these issues by batching queries together, and performing work on the best server for the job. Even if everything runs on one machine, the skills that you'll learn here will help to improve performance by increasing efficiency.

The topics covered in this chapter include the following:

  • The operations that can be slow

  • Select N+1 problems in detail

  • Returning only what you need

  • Writing...
