v1.1.6 - Show latest stable - Class: ActionView::Helpers::BenchmarkHelper

benchmark(message = "Benchmarking", level = :info)

public

Measures the execution time of a block in a template and reports the result to the log. Example:

 <% benchmark "Notes section" do %>
   <%= expensive_notes_operation %>
 <% end %>

Will add something like "Notes section (0.34523)" to the log.

You may give an optional logger level as the second argument (:debug, :info, :warn, :error). The default is :info.
