Abstract
Did you know that inject() and especially all?() iterator nested in another loop can really slow you down? Or that bigdecimal and string comparison is unbelievably slow in Ruby < 2.0? Or that parsed CSV is 13x larger in memory than on disk? Want to know these and other performance hints with in-depth explanations? Want to learn how to use profilers to find what's slow by yourself? Then this session is for you.
