Guassian timer

[Suresh Rajachar <su...@yahoo.com>]

Hi, 

I am using Guassian Random Timer(GRT) in my test plan. 
Surprisingly, the samples are not getting executed in the order they have 
recorded. Some of the threads are not running all the way through the script. 

If i use the constant timer, it works fine. But, i want to use GRT to have 
varieties in think time. 


Any suggestions for this please ?

 
Regards, 
Suresh R

Timers are applied before all samples in scope; in this case all 3 samplers.

Timers do _not_ change execution order within a thread.

There is no guaranteed ordering of samples across multiple threads.

I suggest you check the jmeter log file for errors.

Hi,

Depends what you understand by fine :). It would be easier with an example
of test-plan and what do you expect to happen.

- sample1
- sample2
- sample3
- Timer
- results tree

If timer is constant timer, than they will be executed in the same order.
If timer is gaussian random timer, than it depends on the times. For
deviation=25000, offset=10000, there is no telling what the order would be,
because it randomises the delay timer, that's the whole purpose.
