Thanks for setting up the benchmark in the first place, it has been fun seeing the performance of the different approaches. Nested loops don't scale well. When there were only 2 items for the outer loop it was really fast. I've seen folks here toss around the Big O notation and although I hadn't heard of it before Perlmonks I figured out they were talking about linear growth as opposed to exponential or some other function for the execution time related to the size of the data set.
The nested loop approach seems to be O(n^2) but I'm still learning so hopefully someone will weigh in if I'm off base.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
