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.

Chapter 7. 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:

  • Input/output
  • Network diagnostics
  • Batching API requests
  • Efficient DB operations
  • Simulation and testing...
