Page Caching Resurrected: A Fairy Tale
The document discusses using caching techniques like page caching, action caching, and fragment caching to improve performance of dynamic web applications built with Ruby on Rails. It describes how caching saved pages, fragments of pages, and controller actions can significantly increase the number of requests a server can handle per second by avoiding unnecessary database queries and template rendering. The document also discusses using JavaScript, Ajax, and direct responses from Rack middleware for additional performance gains in Rails applications.
