Throughput

Throughput is the amount of work, requests, records, or data a system successfully completes per unit time; it is not the same metric as latency.

Measurement and Bottleneck Boundary

Throughput is a rate of useful completed work, not a synonym for low latency or high CPU utilization.

Throughput Must Be Read Together with Latency

Higher throughput does not automatically mean a better system. Larger batches or greater concurrency can raise work per second while worsening P95/P99 through queueing. Capacity evaluation should measure operations per second, tail latency and saturation at the same load point.
