You could do the same thing with substr without creating the arrays: 
my $matches;
for my $i (0..length($first) {
   if (substr($first,$i,0) eq substr($second,$i,0)) { $matches++; }
}

I don't know if it would be faster, but it's possible since you wouldn't have the overhead associated with splitting the strings into the arrays. Maybe some interpreter monk knows the answer to that.
