I fail to see what your point is. Now you're comparing two different things. In the single quote case, you're assigning a plain string to a variable - in the double quoted case, you're interpolating an undefined (or did you think a lexical variable in the main program is visible in the Benchmark package?) variable into a string, and assign that to a variable.
So, am I surprised that if you do more, it takes more time to run? Nope. Does it, in any way, invalidate the premisses that there's no performance difference between identical single quoted and double quoted strings? Nope, not in the least bit.
Tell us, what's the point of your post?

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).
