Speed up your Ruby on Rails 4.1 applications . With the help of some gems, all techniques in this course can also be used in Rails 3.2 apps. This course teaches pragmatic, Rails-specific techniques to profile performance, find and fix slow database queries, get alerted automatically whenever you create an N+1 query, and simulate latency and low bandwidth. You’ll also learn to take advantage of the browser’s cache with ETags or time-based expiration, set up Memcached for server -side caching, speed up view rendering with fragment caching, cache nested fragments with R ussian Doll caching, and use Turbolinks and pjax to give a multi-page app the responsiveness of a single-page app.
