Costs are not only on startup time. Memory consumption is cost on process lifetime. And longer GC time is every time when full-GC is happened. So performance is problem for both of short lifecycle applications like CLI tools and long lifecycle applications like Web app. Regards, -- Inada Naoki <songofaca...@gmail.com> _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/ZQE3BXOTCETH6CDMGZHDGDEKV6SRQGQR/ Code of Conduct: http://python.org/psf/codeofconduct/
