Stefan, We are going to release first version of implementation of new relations in graphdb which is sometimes 20x (that is true) times faster than current one. Aslo data structure is used in this relations was tested by Kai Londenberg and he confirmed https://groups.google.com/forum/#!searchin/orient-database/sbtreebansai/orient-database/ltNElAF0H_o/uQOwqAliUH8Jthat even on millions of relations there is no performance degradation.
I attached also early benchmarks, that is benchmark of import or Wikipedia data in OrientDB. Firs line amount of records, second line time spent for insertion of 100 000 records. Full benchmark which we will run during 12 hours will be published at Monday (ridbag is new impl ridset is old impl). About your question in case of more than 50 links (roughly speaking) these links are stored in separate data structure so you should not worry about oversize.
