Response time mismatch while running Selenium in Java VUser

Hi All,

I am trying to execute the selenium script as Java VUser script. When I executed the script, I am experiencing mismatch in the response time of Java VUser script  compared to response time captured in the web script of the same test case. For eg. 90 percentile of Launch the app transaction takes 0.5 secs in web meanwhile same takes 3.5 secs in the Java VUser script.

Please suggest me how to identify the server response time for the same transaction. Any suggestion would be highly appreciated.

Thanks in advance!
