<p>Flat profiles show the total amount of time spent in each method. As an
example, here is the output from running printers_test.rb.</p>

<p>All values are in seconds.</p>
<p>The columns are:</p>
<pre>%self - The percentage of time spent in this method, derived from self_time/total_time
total - The time spent in this method and its children.
self - The time spent in this method.
wait - amount of time this method waited for other threads
child - The time spent in this method's children.
calls - The number of times this method was called.
name - The name of the method.</pre>
<p>Methods are sorted based on %self, therefore the methods that execute the
longest are listed first.</p>
<p>For example, wee can see that Integer#upto took the most time, 0.059
seconds. Method Object#is_prime calls this method, so the 0.59 seconds
appear as child time for Object#is_prime.</p>
<p>The interpretation of method names is:</p>
<ul><li>
<p>MyObject#test - An instance method “test” of the class “MyObject”</p>
</li><li>
<p><Object:MyObject>#test - The <> characters indicate a singleton
method on a singleton class.</p>
</li></ul>
