Is there a way to see how much memory a variable uses?

I am working with Perl for some months now. As for now, my scripts work but they are far from being perfect.

I would now like to optimize the memory usage, thus I am looking for a way to break down the memory usage per variable/hash.

Is there a way to see how much memory a variable uses?

Devel::Size or Devel::Size::Report can be used to get memory usage for a variable/structure.

You might want to check perl guts illustrated to see what the numbers really mean.

Have a look at Devel::Size on CPAN.
