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.

Data compression is a broad topic, and we can't hope to cover it all. Here, we will learn about lossless compression and how to use it in HTTP. We will also cover lossy image compression of pictures later in the chapter. Compression is important because if we can make files smaller, we can shorten the time that it takes to transfer them over a network.

Lossless compression algorithms

You may have noticed HTTP headers from some of the previous screenshots were related to encoding. The most common compression algorithms for HTTP are gzip and DEFLATE, which are very similar. These are both related to the algorithm used in ZIP files. If you do not already use HTTP compression, then this is a quick win, and it will improve the performance of your site if you enable it.

There are many other more advanced compression algorithms, such as xz, which is similar to the 7-Zip (7z) format and uses the Lempel-Ziv-Markov chain Algorithm (LZMA/LZMA2). However, there are currently only two additional...
