Shopzilla site redo

Just watched a nice video from Philip Dixon (Shopzilla) about the performance gains when they redid their site.

The general philosophy is to refactor rather than rewrite. They had a mixed approach by slowly exposing more and more traffic (via load balancing) to the new infrastructure.

Something I didn't realize is the impact of serving static content from cookie-less domains. Sites like yahoo use (I always wondered why they did that!)
