# HTTP Response Time Measurements

The **HTTP Response Time** measures the time from when the client sends an initial HTTP request to the server to the time the client receives the first byte of information in reply from the server. This time does not include the full amount of time needed to transmit all of the data requested, only the time that it takes the server to begin to respond to a request.
