Throughput = be of requests / Total time to air the requests. For a hit request the throughput depends only on the measure to issuea single communicate. For multiple requests the throughput depends also on the gaps betweenthe requests. E g if a request is issued every 30 seconds thethroughput will be 2/min and is largely independent of the measure eachrequest takes.
