Throughput

In general terms, throughput is the rate at which something can be produced, consumed or processed.

Standard deviation does not have any meaning for a dataset that describes latency. It is not relevant.

Organizatorium

• Never average percentiles.
• Coordinated omission.

• Service Time in Queueing Theory.
