Any script using C4::Context is bound to have a huge memory footprint because
of the dependencies.  And even script that would do without C4::Context
(somehow) are bound for the same as soon as they include one Koha:: module,
because those will use C4::Context.

A graph from v23.05 will summarize it better than any explanation:
