First of all, very interesting text. I never have looked the vec() function of Perl very well, but can be very important for a big amount of data.
Well, since vec is a CORE function, that work directly over the bits of the content of a string, it will much more faster, but don't forget that a vector is fixed, each element have the same size, is just an array of chars, and the Perl ARRAY is an array of SCALARS, that are much more complex.

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).
