Throughput (aka. bandwidth)
Throughput is a measure of the amount of work done, or the amount of data processed, in a given amount of time. It is also known as bandwidth and is typically expressed in terms of requests per second (RPS) or transactions per second (TPS).
As a quality attribute of distributed software, trade-offs may be made with latency. For example, to increase throughput you might batch requests together, process data in parallel, or spread load across multiple servers. But these strategies can have the effect of increasing the time individual requests spend waiting in queues, thereby increasing latency. Raising throughput by adding resources does not in itself improve efficiency, which is the ratio of useful output to the resources consumed to produce it.
