ASP.NET Core Kestrel - Adventures in Building a Fast Web Server

Explore the challenges and innovations behind building a high-performance web server in this in-depth conference talk. Delve into the architecture of ASP.NET Core's Kestrel, a cross-platform web server based on libuv that has contributed to ASP.NET Core's impressive 20x speed increase over its predecessor. Learn about advanced techniques for reducing garbage collection, implementing memory pools, and optimizing async/await operations. Discover how the team leveraged AsyncAwaitReadAsync, SocketInput, and memory diagrams to enhance performance. Gain insights into the use of Advanced Vector Extensions (AVX), numerix operations, and efficient loop structures. Examine the intricacies of handling carriage returns, implementing binary search algorithms, and optimizing vector sizes. Understand the rationale behind choosing libuv and its integration into the stack. Uncover the complexities of header field processing and response generation in this comprehensive exploration of modern web server design.
