What is Network Latency?

Network latency, or network lag, is the time it takes for data to be transferred from its source to its destination. Low network latency (meaning very fast data transmission times) is a critical characteristic of a high-performance blockchain or computer network because the faster the network is able to process data, the more suitable it is for large-scale enterprise use. Network latency has a direct relationship to transaction throughput and the number of transactions per second (TPS) a computer network can perform.
