Hi Sriarhei, OrientDB privileges the traversal rather than insertion speed, because in 90% of the cases users do a massive import once and then use the database mostly on lookups.
However we're working to the new implementation of 1-N relationships mush faster. This will impact edge creation speed a lot. It should be available on 2.0-SNAPSHOT in few days.
