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.

Internet protocols


It's important to know about how your HTML and other assets are delivered from the web server to your user's browser. Much of this is abstracted away and transparent to web development, but it's a good idea to have at least a basic understanding in order to achieve high performance.

TCP/IP

Transmission Control Protocol / Internet Protocol (TCP/IP) is the name for a pair of communication protocols that underpin the internet. IP is the lower-level protocol of the two, and this deals with routing packets to their correct destinations. IP can run on top of many different lower-level protocols (such as Ethernet), and this is where IP addresses come from.

TCP is a layer above IP, and it is concerned with the reliable delivery of packets and flow control. TCP is where ports come from, such as port 80 for HTTP, and port 443 for HTTPS. There is also the User Datagram Protocol (UDP), which can be used instead of TCP, but it provides fewer features.

HTTP runs on top of TCP, and it is...
