Please take with a grain of salt.

Take a close look at the overall scorecard. There are a variety of tasks there. On some of these Perl does very poorly. For instance Perl loses on deep recursion. Perl loses on the speed of method calls. On many others there the statement is that all versions must be implemented in the same way. For instance look at the array access example. Perl would improve by a good factor if you replaced the C-style for loop with a Perlish foreach loop.

What this means is that, while the page is certainly food for thought, it is not the final word on your speed in your applications...
