When you are performing image deployment, there is
Check the data transfer mode for the deployment template. If it is set to Unicast, then throttle the bandwidth to 300 MB per second or lower and then deploy the image. Multicast deployment is recommended for multiple machine deployment. With this mode of transfer, the OS Deploy Server sends data to a group of recipients simultaneously. Whereas, using the Unicast transfer mode, the OS Deploy Server sends a copy of the data to each recipient, thereby significantly reducing the deployment speed.
