In my post on calculating throughput and response time I discussed how to measure the average throughput and response time for a given amount of time. I think it’s important to understand how to calculate these averages, but providing a single average causes you to mask other important trends and information about the system behavior.
This is a given in any statistical analysis. We don’t want to publish a large set of data because there is too much information, so we try to extract important information. But if we shrink …

In software, response time measures a client’s perspective of the total time that a system takes to process a request (including latency). The response time of a single request is not always representative of a system’s typical response time. In order to get a good measure of response time, one will usually calculate the average response time of many requests. Response time is usually measured in units of “seconds / request” or “seconds / transaction”. (Note: Don’t confuse response time and latency.)
Throughput is the measure of the number of messages …
