Measuring total time for a thread group execution

[Toby Hobson <to...@btinternet.com>]

<!-- DIV {margin:0px;}-->Hi

I
am trying to measure the response time for loading a page, including
all the css, js and images referenced in it. I have built a thread
group which simulates all the requests the browser will make (using the
proxy tool). Now I am trying to measure the time it takes for the
thread group to run. I have found various listeners like the summary
report which are useful but they all seem to give stats for the
individual samples. What I really need to know is "how long will it
take to load this page". I guess I could just add all the average
sample times together but this isn't really a true reflection of the
real world.

Cheers

Toby

The transaction sampler may help, but it won't be the same as using a
browser, as a browser can do multiple requests in parallel, and JMeter
cannot at present.

But then again different browsers will take different times.

I think you should have a look at the Transaction Controller, and put 
your samplers inside it.
Then use the Transaction Controller option which makes the transaction 
controller return a sample that contains subsamples.
Then I think the transaction controller sample will turn up in your 
listener, and it will contain the total time (sum) of all the 
subsamples, i.e. "total time to load page".
That functionality is present in 2.3RC3, and the latest nightly builds.

Note that browsers often run several downloads (images, css etc) in 
parallel threads, Jmeter does not do that, it executes one sample at a time.
Still you will get a useful kind of a "worst case scenario" time.
