I'm using variable persistence with Data::Dumper. Indentation is set to 0. What is up with this? Why does it's CPU/RAM intensity increase exponentially when the it parses two times the logs? I could understand a good several second increase, but this is rediculous. Is there something I'm missing?

Here is the run: 

C:\Perl>perl stats.pl
0.0400      Data Loaded
0.4200      Lines Parsed: 10347
0.4210      Data Dumped
0.8810      TOTAL ; Finished Execution

C:\Perl>perl stats.pl
0.0400      Data Loaded
1.7620      Lines Parsed: 20337
50.5330     Data Dumped
52.3350     TOTAL ; Finished Execution

.. and the relevant code: 

use Data::Dumper;
$Data::Dumper::Indent = 0;
$encoding = Data::Dumper->Dump(    [\%DATA    ],
                [qw(*DATA)]);

%DATA is a hash of hashes of hashes of strings and integers, basically. (heh)

If nothing can be done about this, what sort of (more efficient) alternatives are there? Preferably as simple as dumping to a file and a 

do "data.dat";
