Latency issues can frequently occur if you haven’t restarted your device in a long time. Throughput: The number of events that can be executed per unit of time. Packet loss is where data packets are lost in transit. However, the strict meanings of the terms are that network delay is the time the first bit in a packet takes to get from A to B, whereas latency is the time it takes for the entire message to arrive at the destination. The more routers a packet has to travel through the more latency there is because each router has to process the packet. Optimization Next: Throughput vs. Latency. Throughput for the purpose of this article will be understood to be measured from the arrival of the first bit of data at the receiver, to decouple the concept of throughput from the concept of latency. The first steps are to draw up a network diagram to map your network and to define a network management policy. As a consequence, the presence of latency indicates that a network is performing slowly. … Throughput is how much data that is sent … and received at any given time. Throughput mode allows devices to receive increased download and upload speeds. One of the most important pieces of information you need to know when measuring network throughput is your network baseline. As much as throughput may be the key to retail sales while latency and IOPS are that of enterprise, this knowledge enables our understanding of why our PC starts in 15 seconds with a SSD , vice that of a minute or more with HDD .
