Response time ( English response time ) means the time between the sending of a message to the computer (for example, by pressing the enter key ) and the reception of the first character of the corresponding response at the terminal .
The response time is made up of the data transmission rate in the transmission media and Internet components, the waiting time and the processing time of the message.
Factors influencing the response time can include:
- During data transmission: network performance ( efficiency ) and network load
- When it comes to the waiting time: backlog at high request rates
- In terms of processing time: computing power (performance) of the computers and the database system , quality of the database design and software .
In addition to availability , response time behavior is an important indicator for evaluating the user-friendliness of communication systems. Since the user-friendliness per se cannot be measured, criteria must be described that can only apply to a specific application. They depend on the expectations of the user group .
The response time is a value when calculating the response ratio .
