What perl are you using? Those should be identical at runtime, since interpolation is converted to concatenation by the tokenizer. For evidence, try:

% perl -MO=Deparse -e '$foo=q(foo)'
$foo = 'foo';
-e syntax OK
% perl -MO=Deparse -e '$foo=qq(foo)'
$foo = 'foo';
-e syntax OK

I ran your benchmark program, and got +/- 3%. Try running it a few times.

I was logged in remotely to my home machine when i ran this, which means that xscreensaver was running with 100% of my cpu (yay OpenGL). I ran the test again without xscreensaver and i got the same results you did. oh well.

I wonder if the results have anything to do with you using q instead of a single quote and qq instead of double quotes.
