Ignoring transmission time for a moment, the response time is the sum of the service time and wait time. The service time is the time it takes to do the work you requested. For a given request the service time varies little as the workload increases – to do X amount of work it always takes X amount of time.
under 0.1 seconds the response is perceived as instantaneous (high user satisfaction); 1.0 seconds between 0.1 seconds and 1.0 second a slight delay is perceived, which is regarded as annoying in a local system but tolerated in a web interface that depends on a remote system for the response; this kind of delay usually does not interrupt user's ...
The response times are the times required for an application to respond to a user's actions at such a load. [2] The second set of performance metrics measures the computational resources used by the application for the load, indicating whether there is adequate capacity to support the load, as well as possible locations of a performance ...
In telecommunications, round-trip delay (RTD) or round-trip time (RTT) is the amount of time it takes for a signal to be sent plus the amount of time it takes for acknowledgement of that signal having been received. This time delay includes propagation times for the paths between the two communication endpoints. [1]
One component that makes up the response time is the time spent executing the software – hence if the software worst case execution time can be determined, then the designer of the system can use this with other techniques such as schedulability analysis to ensure that the system responds fast enough.

In queueing theory, T i is called the interarrival time, and C i is called the service time. These two parameters are often specified as rates: These two parameters are often specified as rates: λ i = 1 T i {\displaystyle \lambda _{i}={1 \over T_{i}}} is the arrival rate , and
Rates on a 15-year mortgage stand at an average 6.32% for purchase and 6.34% for refinance — up 3 basis point from 6.29% for purchase and 5 basis point from 6.29% for refinance this time last week.
