Re: Simulate Think Time
Hi,
Found a problem applying simulated Think Time --
- I don't want the simulated Think Time be calculated/included in my
response time
- So I put it after my request, not under it
- However, I put only one such Think Time but *every *single request is
now delayed, because it is actually *at the thread group level*.
- That in turn caused a bigger problem for me, as I only want Think Time
delay *after *each of my *transactions*, but not the requests
*within *those
transactions.
- I.e., if a single click of "submit" contains several requests, I want
those requests executed without any delay, but only do Think Time after
all those requests are done.
How to achieve all of the above please?

Hi Tong,
"

now delayed, because it is actually *at the thread group level*.
"
What element(s) are you using to simulate Think Time? You can not just use Timer elements on their own.
"
- I.e., if a]] single click of "submit" contains several requests, I want
those requests executed without any delay, but only do Think Time after
all those requests are done.
"
All of those requests should be in a Transaction Controller, and then after that there should be a Flow Control Action (https://jmeter.apache.org/usermanual/component_reference.html#Flow_Control_Action) with a Timer (e.g. https://jmeter.apache.org/usermanual/component_reference.html#Uniform_Random_Timer) element inside. You can right click the Thread Group or a Controller and select "Add think time to children" to generate this for you. Then duplicate/move the Flow Control Action(s) to where they need to go (i.e. outside of/before/after the transaction controller). Ensure you've provided correct values for Random Delay Maximum and Constant Delay Offset
Thanks,
Malachi

If you're simulating "Think Time" usingJMeter Timers
<https://jmeter.apache.org/usermanual/component_reference.html#timers>
be aware that they:
1. Obey JMeter Scoping Rules
<https://jmeter.apache.org/usermanual/test_plan.html#scoping_rules>
2. Are executed *before* each Sampler
<https://jmeter.apache.org/usermanual/component_reference.html#samplers>in
their Scope
If you want to introduce the delay **after** the Sampler you will need to:
* either use Flow Control Action sampler
<https://jmeter.apache.org/usermanual/component_reference.html#Flow_Control_Action>(you
will need to copy and paste it after each Sampler where you want to
add "think time")
* or go for something like JSR223 PostProcessor
<https://jmeter.apache.org/usermanual/component_reference.html#JSR223_PostProcessor>with
a very simple Groovy code
<https://www.blazemeter.com/blog/apache-groovy> like sleep(1000),
like Timers this guy obeys JMeter scoping rules and the
PostProcessor will be executed after each Sampler in its scope so
single PostProcessor will be sufficient to add a delay after each
Sampler
