Hi,

I added another version, that split string that split with a smaller last chunk. Added also a /o, to improve performace (that can be used if you have several lines to split.

Added this to the benchmark:

'regex' => sub { my @arr = $string =~ /(........)/g; }, 'regexo' => sub { my @arr = $string =~ /(.{1,8})/og; },
The results:
