- about the same number of Perl programs are faster than the Ruby 1.9 programs by about the same amount, as there are Ruby programs faster than Perl programs
- some of the Perl programs use half the memory of the corresponding Ruby 1.9 programs
- the Perl programs and Ruby 1.9 programs use about the same amount of code.
It must be the spectacles you're looking through.
