Most of the big Web 2.0 websites rely on memcached (pronounced "Memcache-Dee") to scale, even the ones not using Rails. In this screencast you’ll learn how easy it is to use memcached in your Rails application, and how to do low level query caching for websites where you have highly customized layouts.

Before we can talk about Server-side performance, we need to go over Client-side performance.  We’re talking about how fast your website comes up in a user’s browser.
