Hello karlgoethebier,

You are absolutely right. I also read the Benchmark/Optional-Exports where is clearly stated:

cmpthese ( COUNT, CODEHASHREF, [ STYLE ] )

Optionally calls timethese(), then outputs comparison chart. This:
    cmpthese( -1, { a => "++\$i", b => "\$i *= 2" } ) ;
outputs a chart like:
           Rate    b    a
    b 2831802/s   -- -61%
    a 7208959/s 155%   --

This chart is sorted from slowest to fastest, and shows the percent speed difference between each pair of tests. cmpthese can also be passed the data structure that timethese() returns:

Thanks for correcting me I will also update my answer. Although to be honest I am kind of impressed how unpack is slower in comparison to substr and split.

Thanks again for your time and effort, BR.
