JMeter Loading time showing wrong reading

Question

I am new to Jmeter , actually I was trying to check the loading time taken for each page in my php application. I used highcharts API for the graphs. When clicking on data menu it will list out all the six graphs. I used Blazemeter chrome extension to record the loading time taken for the six graphs. Once loading time is recorded for each graphs i export the file with .jmx extension which is available in Blazemeter and imported in JMeter and started with iteration for one user, two users , five users and ten users. But when i was checking manually the second graph is taking more time for loading , approximately 7 Secs. But in my JMeter, loading time is shown as 0.534Secs for one user. Please anyone help me how to check the loading time for graphs. with regards, T.Ragith

Answer 1

This is most probably due to JavaScript-driven requests in your application, i.e. it uses AJAX technology.

As per JMeter project main page JMeter doesn't execute JavaScript found in the webpage, you need to either find a way to kick off the same requests real browsers do or switch to real browsers for your load testing via JMeter WebDriver Sampler.
