Tracing your way through Ruby, by Elise Huard

When a ruby program gets awfully slow and you don't know why, or you have a segfault out of the blue, or your memory usage is strangely high, it's time to open other drawers of the toolbox. This talk presents an overview of the most interesting tools which allow us to have an insight in what's happening in ruby when we run a program. To name but a few: perftools.rb, dtrace, instruments, and debugging the ruby code itself. Standing on the shoulders of giant: it works. Barcelona Ruby Conference is a conference held by Codegram.
