Analyzing the Production Log
In order to improve performance of your Rails application you need to find the bottlenecks. A great starting point is your production log. In this episode you will see how to use RAWK to analyze your log file and determine which controller actions take up the most processing time.

Action Caching
Action caching behaves much like page caching except it processes the controller filters. You can also make it conditional as seen in this episode.
(7 minutes)
Fragment Caching
Sometimes you only want to cache a section of a page instead of the entire page. Fragment caching is the answer as shown in this episode.
(6 minutes)
YAML Configuration File
Application configuration shouldn't be spread throughout your code base. Instead a much better place to put it is an external YAML file. See how to do that in this episode.
