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.

SIMD CPU instructions


Single Instruction Multiple Data (SIMD) is a technique that is available on many modern processors and can speed up execution by parallelizing calculations even in a single thread on one core. SIMD takes advantage of additional instructions available on CPUs to operate on sets of values (vectors) rather than just single values (scalars).

The most common instruction set for this is called Streaming SIMD Extensions 2 (SSE2) and it has been around for over 15 years since its debut with the Pentium 4. A newer instruction set called Advanced Vector Extensions (AVX) offers superior performance over SSE2 and has been around for over five years. So, if you're using a reasonably recent x86-64 CPU, then you should have access to these extra instructions.

Note

Some ARM CPUs (such as those in the Raspberry Pi 2 and 3) contain a similar technology called NEON, officially known as Advanced SIMD. This is not currently supported in .NET, but may be in the future. An official open source...
