A test with simple loop is meaningless.
This is my result (with ruby-1.9):

$ cat runperfor.rb 
i = 10_000_000
while i > 0
     i -= 1
end

$ cat runperfor.pl 
$i = 10_000_000;
while ($i > 0) {
     $i--;
}

$ time ruby runperfor.rb 

real	0m1.022s
user	0m0.992s
sys	0m0.000s

$ time perl runperfor.pl 

real	0m1.652s
user	0m1.600s
sys	0m0.008s
