Devel::Size - Perl extension for finding the memory usage of Perl variables
use Devel::Size qw(size total_size); my $size = size("A string"); my @foo = (1, 2, 3, 4, 5); my $other_size = size(\@foo); my $foo = {a => [1, 2, 3], b => {a => [1, 3, 4]} }; my $total_size = total_size($foo);
This module figures out the real size of Perl variables in bytes, as accurately as possible.
