Excerpt

Viewing from above, a web server isn't a particularly difficult piece of software: requests come in, responses come out. When high performance and scalability are desired, though, it is a completely different story. This talk will tell the story of Lwan, a web server written from scratch, and some of the tricks involved in making it as fast as it is.

Description

In development for over 2 years, Lwan was until now a personal research effort that focused mostly on building a solid infrastructure for a lightweight and speedy web server. It is now slowly transitioning into a fully working, capable HTTP server.

This talk will present various milestones of the project, showcasing implementation tricks and architectural decisions used to achieve them.

Speaking experience

Leandro has spoken at various conferences, including FOSDEM, Embedded Linux Conference, Tizen Developer Summit, Fórum Internacional de Software Livre, Python Brasil, etc.

Subjects are usually what I've worked on the previous year, which may or not may be weekend projects.

This will be the first time I'll be talking about Lwan to a large audience.
