Low Latency (capital Markets) - Latency Measurement - Terminology - Throughput

Throughput

Throughput can be defined as amount of data processed per unit of time. Throughput refers to the number of messages being received, sent and processed by the system and is usually measured in updates per second. Throughput has a correlation to latency measurements and typically as the message rate increases so do the latency figures. To give an indication of the number of messages we are dealing with the “Options Price Reporting Authority” (OPRA) is predicting peak message rates of 907,000 updates per second (ups) on its network by July 2008. This is just a single venue – most firms will be taking updates from several venues.
