+    # in a template.
+    module BenchmarkHelper
+      # Allows you to measure the execution time of a block 
+      # in a template and records the result to the log. Wrap this block around
+      # expensive operations or possible bottlenecks to get a time reading
+      # for the operation.  For example, let's say you thought your file 
+      # processing method was taking too long; you could wrap it in a benchmark block.
+      #
+      #  <% benchmark "Process data files" do %>
+      #    <%= expensive_files_operation %>
+      #  <% end %>
+      #
+      # That would add something like "Process data files (345.2ms)" to the log,
+      # which you can then use to compare timings when optimizing your code.
+      #
+      # You may give an optional logger level as the second argument
+      # (:debug, :info, :warn, :error); the default value is :info.
