I would try adding an index on (objectid, start) and another on
(objectid, end) and see how that first query does.  Also, if id is a
unique identifier, I'd recommend a unique constraint or (better) a
primary key definition.  Check the system tables to see whether all
the existing indexes are actually being used -- if not, drop them.
