Book

I'm the author of ASP.NET Core 2 High Performance, a book about creating fast, scalable, and high performance web applications with C# and ASP.NET Core 2.0 (an open source and cross-platform framework from Microsoft).

Although many of the examples focus on ASP.NET, it is also a big collection of general tips and experience applicable to making web apps perform well with any language or framework. It covers images, compression, architecture, networks, cloud hosting and even a bit of team culture.

Second Edition

The second edition, fully revised and updated for ASP.NET Core 2.0, is available to pre-order now.
