JMeter latency vs load time(sample time)

Latency is a difference between time when request was sent and time when response has started to be received.

Response time (= Sample time = Load time = Elapsed time) is a difference between time when request was sent and time when response has been fully received.

So Response time always >= latency.

The larger file is, the larger difference between response time and latency will be.

Latency = 922 ms means that it takes 922 ms as the first response of the request from when the request has been made.

Sample Time(or Response Time) = 1232 ms means that it takes 1232 ms to process the request from when it has been made.

Therefore, Response Time = Latency + Processing Time
