Jmeter delay versus actual browser load test

Question

Is this a valid test to verify how long it takes to download a web test using 500 concurrent users.

I run jmeter with a user of thread 500, rise time = 50 and the number of cycles forever. with a listener with "results in a table" that also record the delay.

While jmeter is working, I am trying to download / check the web test using the actual browser (in my case IE8) and it loads after 7 seconds. but based on latency, most results are 50k ++.

- The loading time of 7 seconds in the actual browser is a “response time result”? since this is a download in a real browser.

another question: is 50k latency converted to sec? means 50sec. download web test if we are based on jmeter result? kindly clarify this to me please :)

Answer 1

In simple words, Latency is network latency (time spent by the network in transmitting data)

In JMeter, the wait time is the time when the request is sent to the server until the first byte of the response reaches the client / Jmeter. If the response time is very low, then you will not get an accurate measure of latency. If the response time is long, you may get the right measure.

In Jmeter, Latency is divided by measure as response time, i.e. ms / sec

Your 7sec in the browser (response time (processing time + latency) + rendering time) . In Jmeter, there is no rendering time (since it is not a browser). Although your rendering is very small compared to the response time, but in cases where the time spent on the content is significantly comparable. Therefore, it should be considered.

Hope this removes your doubts :)
