vSphere Replication is very slow. I am trying to replicate VMs as we are trying to move out data enter to a virtual data centre (we will be renting computing and storage). My hosts are ESXi 5.0, vCenter 5.1 and vSphere Replication software that works with ESXi 5.0 and vCenter 5.1. I am trying to migrate VMs from a cluster to a stand-alone host which has its own storage and two data centres are connected via a 300 Mbps connection. I am averaging 512 Kbps only for the replication.
