Ruby 2.1: Profiling Ruby

I wonder if this API allow will foster a big movement to track down all the performance-hungry calls in say, Rails, and help the framework move forward in terms of efficiency. This is really a welcome addition anyway.

I think TRWTF here is that checking for (query string?) parameter existence runs a regexp...

So, I'm a Ruby neophyte. Why did adding parenthesis speed that line up so much?

Why is line level profiling so non-existent for dynamic languages? Function level just doesn't cut it, esp. w/ the zillions of monkey patches in Ruby.

At first I didn&#x27;t realize OP was a GitHub employee and thought he was munging his company&#x27;s GHE appliance :o<p>Cool read!
