You could use Storable, just freeze the structure in memory and print its length, i.e.

use Storable;

my %a = (
'a' => 'something..',
'b' => 'something else..',
)

print length(Storable::freeze(\%a))."\n";

This will give you a "rough ball-park sizeof" without the memory overhead of using a module like Devel::Size :-)

Well, that would give the size of the Storable image of the data, not the live-in-RAM size... and I think the OP intended the latter. So, for the OP: use Devel::Size, or study the sources... -- dakkar - Mobilis in mobile Most of my code is tested... Perl is strongly typed, it just has very few types (Dan)	[reply]
