For a few years now, Ruby on Rails has focused relentlessly on client-side performance. While performance zealots have turned their attention on squeezing out a few more milliseconds on the sever-side, the Rails core team took the advice of the YSlow team seriously very early, building defaults into the framework to increase the default performance of Rails web sites, as well as making it easy to opt-into higher performing techniques very late without requiring a change in site architecture.

Rails 3 adds more high-performance features, and makes Rails even faster out of the box. In this talk, Yehuda will cover the ways that Rails already builds in fast by default, and briefly discuss how Rails will continue to lead the “fast by default” field in the upcoming releases.
