Rails 4.1 Performance Fundamentals

by Brian Morearty

Speed up your Ruby on Rails 4.1 (and 4.0 and 3.2) applications. This course covers profiling techniques; making fewer, faster, database queries; Russian Doll caching; Turbolinks and more.

What you'll learn

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 Russian Doll caching, and use Turbolinks and pjax to give a multi-page app the responsiveness of a single-page app.
