Junaid, what did you set the the network rate to in the exchange service offering? Depending on your backend network setup for that offering you may get better results with setting it to a '0' for unlimited. On my internal CCP, our SQL servers service offering has network rate to '0' as I am using a 4 NIC LACP bond.
