Calculate Average Response time Calculation in JMeter

(Attached as image)

"In My summary report Total Samplers = 11944 My total Average response = 2494 mili-second = 2.49 seconds.

What i understand from here 11944 samplers are processed in average of 2.49 seconds.That means my test actually should processed for 11944 x 2.49 Seconds = 82 hours.But it actually ran about 15-20 mints max.

So trying to understand,is it reduced execution time due to JMeter parallel/multiple thread execution or i am understanding it wrong way.

I want to know a single request average response time"

JMeter calculates response time as:

• Sum of all Samplers response times
• Divided by the number of samplers

basically it's arithmetic mean of all samplers response times.

11944 x 2.49 / 3600 gives 8.2 hours and yes, this is how much time it would take to execute the test with a single user, the amount of time will reduce proportionally depending on the number of threads used
