Couple of words about benchmark. We imported wikipedia data using OrientGraph database, to be sure that we have no duplications unique index by page key was created.
First benchmark that is benchmark which uses 1.6.4 version of OrientDB and second benchmark uses version from https://github.com/orientechnologies/orientdb/tree/rid-set-sbtree branch.
