However, if your system back-up is to a remote site that is a considerable distance away, you might be using only a small percentage of the bandwidth that you're paying for. When your security cameras are transferring video to recorders that are remote or are using a wireless connection, the delivery could be slow or interrupted.
There are two primary reasons for poor TCP performance: significant delay (network latency) and network loss. Yes, TCP is designed to retransmit lost data segments, but they will probably be delayed. In the scenario of a long circuit, the resulting higher delay tells TCP that it must limit its rate of transmission so it won't overwhelming the receiver's buffer.
