How to measure method efficiency in lisp?
<p>For example, in Prolog <a href="http://www.swi-prolog.org/pldoc/man?predicate=time/1" rel="nofollow noreferrer"><code>time/1</code></a> can be used in order to measure the amount of inferences a method call produces.</p>

<p>Is there something similar in Lisp to measure the efficiency of a method to another? That would be extremely useful.</p>

<p>Thanks in advance for the help!</p>
