スループット

定義

一定時間内にネットワークまたはシステムを通じて実際に転送されるデータの速度で、ビット毎秒またはバイト毎秒で測定される。

解説

Throughput is always less than or equal to bandwidth due to protocol overhead, packet loss, retransmissions, and congestion. A 1 Gbps Ethernet link typically achieves 940–960 Mbps of usable TCP throughput. Disk throughput and network throughput are both critical bottlenecks in data center design. The difference between advertised bandwidth and measured throughput is a common source of consumer frustration.
