CALCULATIONS

Recommended Posts

Guest Hari

We are doing performance testing for web based application.

 

WE ARE USING WAPT 3.0

 

Below are the results given by wapt tool.

 

Virtual users: 5

Iterations: 1

Delays between pages: No

Load level limit: N/A

Timing mode: Web transaction (including images)

--- Basic statistics ---

 

Page name: page_1 page_2 page_3 page_4 page_5 page_6 page_7

Min web transaction (including images): 244.21 23.23 15.67 16.7 15.21 4.84 28.31

Avg web transaction (including images): 258.94 26.19 20.58 24.04 17.85 5.64 39.22

Max web transaction (including images): 277.73 27.93 26.78 33.47 22.16 8.73 57.46

3 7 906 7.73 129.43

4 7 1047 6.69 149.57

User/Iteration page_1 page_2 page_3 page_4 page_5 page_6 page_7

001/00001 258.6 26.15 25.65 19.31 15.21 4.84 36.3

002/00001 266.71 23.23 26.78 16.7 19 4.96 28.31

003/00001 247.43 26.2 16.36 33.47 15.92 8.73 57.46

004/00001 244.21 27.93 15.67 27.39 22.16 4.84 41.05

005/00001 277.73 27.42 18.46 23.34 16.94 4.84 32.98

 

 

1. How the tool is calculating the time of AT/S AND AP/S?

2. how can we check the same in the given results?

 

 

FOR EXAMPLE---

EXAMPLE

 

Virtual Users statistics:

User Pages Time AP/S AT/P

1 46 2137047 0.02 46457.54

 

AP/S: Average Page/Second = Pages/Time (in seconds)

 

1000 ms = 1 s

2137047 ms = 2137047/1000 s = 2137.047 s

 

Therefore, AP/S = 46/2137.047 = .021

 

 

Most of the cases AP/S –we are getting correct but if we are checking the AT/P (AVERAGE TIME PER PAGE) is not matching.

Hi,

 

Virtual Users statistics:

User Pages Time AP/S AT/P

1 46 2137047 0.02 46457.54

 

AT/P (average time of page load): in this case it is calculated as Time/Pages=2137047/46= 46457,54ms (the same in the table).

 

AP/S (average number of pages per second): Pages/Time=46/2137,047s=0.021. In the table you have 0,02, which is the same.

 

So it seems that there are no errors in your results.
