If you are talking about the routing and DHT behind Holesail then no, it is very efficient as the underlying tech is based on Kademliya algorithm: 

Kademlia contacts only  𝑂 ( log ⁡ 𝑛 ) nodes during the search out of a total of  𝑛  nodes in the system. 

 which is very little different from standard IP routing with subnets on interfaces of routers
