twn opened a new issue, #6496:
URL: https://github.com/apache/jmeter/issues/6496
### Expected behavior
I expect that transaction sample elapsed time is the sum of child sample
elapsed times excluding thread pause times which should be counted as idle time
for the transaction. (Include duration of timer and pre-post processors in
generated sample is set to false)
Alternatively the success flag could be set to false for the transaction.
This was working as expected in JMeter 2.9
### Actual behavior
As long as the threads are not stopped the behaviour is as expected.
But during ramp down or thread stop the pause times seem to be added to the
transaction elapsed time, which is wrong and produces bad performance results.
Sample during normal execution:
<sample t="924" it="30012" lt="0" ts="1755001448003" s="true"
lb="Transaction Controller" rc="200" rm="Number of samples in transaction : 3,

### Steps to reproduce the problem
Execute the attached TestPlan.
open the generated rampdown-requests.xml and have a look at the elasped time
of the last samples.
