You should definately look into Benchmark. I was able to reduce your test down to this, and I get the CPU usage
use strict;
use Benchmark;
timethese(1500000,
{
'unpack' => 'unpack "H*", "abc"',
'sprintf' => 'sprintf "%x%x%x",ord("a"),ord("b"),ord("c
+")'
}
);
The Results:
Benchmark: timing 1500000 iterations of sprintf, unpack...
sprintf: 0 wallclock secs ( 0.17 usr + 0.00 sys = 0.17 CPU) @ 88
+23529.41/s (n=1500000)
(warning: too few iterations for a reliable count)
unpack: 10 wallclock secs ( 9.87 usr + 0.01 sys = 9.88 CPU) @ 15
+1821.86/s (n=1500000)
ACCCK!!!Abigail-II caught me in a latenight brain seizure. I shoulda been tipped off by sprintf winning. :( ++Abigail-II

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).

are good places to start.
