Ethernet ports transfer data at rates up to 1000 mbps.
A faster device bandwidth can improve response time by enabling quicker data transfer rates between the device and the network. Smaller message sizes can also reduce response time as they require less data to be transmitted. Conversely, slower device bandwidth and larger message sizes can increase response time due to longer transfer times.
