  If by the new routing algorithm, you mean the buffer insertion,
  in fact, it should slightly decrease the density (the inserted
  buffer increase the area).
    As long as the routing complete, this kind of density is not
  a problem. It reflect the highly connected nature of the netlist
  and the effectiveness of the routing.
