# some questions about the curve results of gatling

Hi,

I have some questions about the two curves of results after a bench mark operation with gatling

As you can see , I have attached with this email one curve image of nbr-transactions.png and an other curve image of repsonse_time.png

In the image of nbr-transactions.png, I suppose that at this instant t , we get 64,5 transactions per second with 60 Vusers connected simultaneously to the application.

And with ther image of repsonse_time.png, I suppose that at this instant t, the response time varies between 750 ms to 3590 ms

therefore, Can you explain why in one side we can have an exact value (64,5 transactions per second) and on the other side, we have a range of values (750 ms to 3590 ms)?

Also, Can you explain the meaning of the values in the reponse time table ?

Mean wants to express the average time ?

Std Deviation wants to express ?

95 th percentile wants to express ?

Thanks a lot for your help

in one side we can have an exact value (64,5 transactions per second)

that a point: how many transactions were complete during this second. You
don't get an exact value because we limit the number of dots (see
gatling.conf), so that's an average value.

and on the other side, we have a range of values (750 ms to 3590 ms)?

At one given time, response times were in this (min, max) range

Also, Can you explain the meaning of the values in the reponse time table ?

Mean wants to express the average time ?

Std Deviation wants to express ?
