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.
