With everything else, you have to take this with a grain of salt, but I did what my favorite past time is when I want to see if one thing is faster than another and I Benchmark'd it. The difference is in the buffering since there is output being sent to a filehandle. I ran this about 10 times and these are the average results. (Most of the output has been removed for brevity). So using the following code, I got the following results:
use Benchmark qw(cmpthese);
my $tests = -25;
sub single { print 'This is a test'; }
sub double { print "This is a test"; }
cmpthese($tests,{
single => \&single,
double => \&double
});
__OUTPUT__
Rate single double
single 1952135/s -- -16%
double 2313034/s 18% --
As has been pointed out in other posts, the difference is nominal.

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).
