I think the optimization I refered to (if you have several instances of the same class in a pickle, then they all share a single instance of the class name and reference this one) is already used. You mean an optimization to make the pickle size for some new style classes smaller. That's not yet used because it could make the storage exchange between different Python versions impossible (the older Python versions would not understand the new pickle protocol). -- Dieter _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
