Using "I" versus "O" BTrees makes a huge difference for mass operations (as those used for cataloguing and set operations). The difference is surely much smaller for "I" versus "L" BTrees -- but it will be measurable for many catalog searches. -- 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
