Python is slower than Perl?

This benchmarking test shows that Python is over twice as slow as Perl. How can this be?

I've hacked enough examples from that "shootout" to understand its written by retards who don't know how to optimize anything.
You can say "Java is faster than Fortran"(its in the data), because someone didn't bother optimizing the Fortran versions.
