It depends more on the frequency and size of session updates. With the DeltaManager traffic volume is proportional to n(n-1) where n is the number of nodes. With the BackupManager it is proportional to n. With 8 nodes the DeltaManager generates 7 times the cluster traffic that the BackManager generates. Whether your network will cope with that will depend on the app and usage pattern.
