Latency The other important performance characteristic of a network is latency. Latency is the amount of time between the sending of a packet on the network and the time at which it is received at the destination. Latency is an important factor because of how much time it takes to receive a response from a server on the Internet. The more requests that a server has to process, the longer the response times are going to be. To measure the latency, we use the Nperf Ping benchmark and Nperf Traceroute benchmark. The Nperf Ping benchmark measures the round-trip time between a server on the Internet and the network interface. The Nperf Traceroute benchmark measures the latency from a client to a server on the Internet. We also measure the latency to a location in our network with the Nperf Latency benchmark.
