> {{org.apache.jackrabbit.oak.jcr.LargeOperationIT#largeCopy}} does not scale linearly with the number of copied nodes in the case of document:
> {code}
> quotients: 1.1803765754650501, 0.33168970806199227, 0.8160753821577706, 1.4619226777374157, 1.9342440796702938
> {code}
> Note how copying trees with 32768 and with 131072 nodes each took super linearly longer than copying the respective previous amount of nodes. See also OAK-1413 on how to read these numbers.
