Subject how to simulate asynchronous calls..
Date Fri, 20 Apr 2012 08:45:03 GMT

please help me in understanding the below mentioned situation...let me know
whether it is possible to do so or not..

in my application(flex application) test plan contains the following

--thread group
-------home(transaction controller)
-------login(transaction controller)
-------drilldown(transaction controller)
-------uploadfile(transaction controller)
-------downloadfile(transaction controller)
-------logout(transaction controller)

there are some samples in few transactions which are asynchronous.....

1) is it possible to send few samplers in a controller at a
time(simultaneously)...i feel that the samplers in jmeter are send one by
one..(correct me if am wrong) it possible to simulate few samplers in a
transaction at a time.
as per my understnading using synchronizing timer will wait for remainig all
the threads to reach that state...and call will made to that by all users at
a time.
i want to acheive the similar act within a transaction controller.

2)when i run the test with single user without giving any delay/deviation in
my gussian random timer ..i got results in aggregate report are...

and when provided some deviation in timer the values varies ...

i am very confused with this....
can some one explain me how j meter calculates the response times?
does using different controllers vary the response times?

 waiting for your valuable suggestions:(
