Well of course benchmarking may prove me wrong but I would have thought that slurping the contents into the array and then iterating over the array is going to be less efficient than simply reading the file line by line like: 

...

while(<DATA>)
{
  ...
}

You probably also want to avoid using DATA as a filehandle as this is a predefined handle setup when Perl initializes pointing to the the stuff after an __END__ or __DATA__ at the end of the program. It doesn't break anything but might be confusing to someone reading the program later.
