Volume Replicator uses the network to replicate data from the Primary to the Secondary. The Bandwidth Throttling feature enables you to control the maximum network bandwidth that Volume Replicator uses for replication. Bandwidth Throttling controls the rate at which data is sent from the Primary to the Secondary; it does not limit the rate at which the network acknowledgments are sent from the Secondary to the Primary.

By default, Volume Replicator uses the entire available network. However, you might want to control the bandwidth that Volume Replicator uses depending on factors such as, whether other applications can use the available network connection or is it exclusively for Volume Replicator, the network costs, and network usage over time. For example, if the network is used for purposes other than replication, you might have to control the network bandwidth used by Volume Replicator. Volume Replicator enables you to change the network bandwidth that is used for replication to the Secondary, even when replication is in progress.

If you want Volume Replicator to use the entire available network bandwidth then do not set any value for the bandwidth parameter either using the GUI or command line.
