Erik Michaels-Ober - Writing fast Ruby

This is a talk from Barcelona Ruby Conference 2014 (http://www.baruco.org/). Performance is one of the most important features of any application. Research has shown that every 100 milliseconds decrease in speed can reduce sales by 1 percent. Ruby is not known as a fast language but there are things we can do to optimize the performance of our Ruby code. This talk will show how to properly benchmark your Ruby code and discuss various techniques for making code faster and more memory efficient.
