How do you calculate response time?

Thus, the calculation of response time is: Tresponse = n/r - Tthink = (5000/ 1000) - 3 sec. = 5 - 3 sec.

How does JMeter calculate sample time?

Response time (= Sample time = Load time = Processing Time + Latency Time) is a difference between time when request was sent and time when response has been fully received. Save this answer.

What is JMeter load time?

However, there's an important difference between these two. Latency is defined as the time from just before sending the request to just after receiving the first part of the response, whereas load time is the time from just before sending the request to just after receiving the last part of the response.

Response time is also known as time to last byte while Latency is time to first byte:

  • Time to last byte - time from the moment the request was sent till the last resource is finished downloading.
  • Time to first byte - time from the moment the request was sent till the first byte of the first resource is received back.

Is that what you wanted to know or have I misunderstood your question?

EDIT:
Here is a more detailed explanation off all possible performance measurements.
