Your post seemed to be incorrect. I don't believe you are interpreting the output in the right fashion. The double still shows up as being FASTER, abnormally faster with your example.

use warnings;

use Benchmark("cmpthese");

cmpthese(-1, {
   "double", q !eval q {$a = "this is a string" x 10}!,
   'single', q !eval q {$b = 'this is a string' x 10}!,
});

Not just did it show a speed increase but 46%, a quite significant one:

Rate double single
double 39422/s -- -31%
single 57420/s 46% --
