It makes no sense to measure WDS virtually, because the virtual machines got ready at different times. That’s because multicast process deploys and the installation takes part “offline” so it is not like fog, that all machines get ready at the same time with multicast. Tomorrow i can test multicast performance but only with an 100 MBit switch.
For sure it can be said fog is quicker with 1 Gbit both in backup and deployment.
