I think this depends on what objects and object counts are in the database. In a 2T database, just pulling data + indexes over to a new database took about 20 hours (using pl/sql and dbms_metadata). The final exp/imp full to add the remaining objects added 10 hours. (a database with more than 1000000 synonyms ....)
