The document discusses how Vox, a large-scale, fast, internationalized website, is built using various web technologies. It uses Catalyst as its web framework, Data::ObjectDriver for caching and partitioning data across multiple databases, Perlbal for fast static content delivery, and Memcached for caching. Template Toolkit templates are optimized through versioned caching and syscall reduction. Asynchronous job queueing and ID allocation improve performance and scalability.
