Nginx is my favourite web server after using Apache for years. It's easier to set up and administer once you get your head around it, and it's blazing fast. It can serve static content incredibly quickly, and its support for caching and other performance-enhancing features is second to none. Plus, it's lightweight and scalable, so it'll never slow down your site, no matter how much traffic you get. In short, if you're looking for a high-performance web server, Nginx is the way to go.
