There will likely be just a few .mv files in the stdlib and they'd all get loaded at Python startup time. A package's .mv file would only get loaded when the package gets imported. Once read I don't think we'd need to stat for those or read them again. It would definitely be worth measuring, but my guess is the additional overhead will be negligible. - -Barry -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iQCVAwUBRe9OhnEjvBPtnXfVAQLjYAP7BeVkCMGCVeVt/oqIoywtyP1+B4Ndgmdo uj0JQUSmu2ikRXRoSNtNSoSKdQsco9FI+LHYHwBRJmLKC+IIZ0glP/y+re6hkdOa vWfj1QLYBzWY6EzXRgf92xiR9dXJx92vsiSWAjibRwLlE7d+3eFYqrBa+fvEzQGv pkKjOlTYIKo= =5OL3 -----END PGP SIGNATURE----- _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
