See the other thread, it does not seem to work

It should be feasible if a variable is used in PTT throughput.

Hello Vladimir,
>From schema that Vincent sent in another thread , I guess what is requested
here is ability to do steps:
- Step 1 : X req/s
- Step 2 : Y req/s
- Step 3 : Y req/s
I am not sure it is feasible with PTT.

I'm afraid I don't follow you here.
Can you please clarify why the current Precise Throughput Timer does not
work for your "pacing" scenario?

Hi,

*If we had notion of try/finally, it could be doable and solve also other
requirements like ensuring a session is disconnected even if error occurs*
Yes if we can set a module controler or test frament for the finally is
could be a good solution for logout or for compute by groovy code the

Vincent,
I'm not sure why do you call it pacing, but what you draw is exactly what
JMeter's Precise Throughput Timer is doing.
If you place the timer under a "flow control action" which is before
sampler1, then the timer would delay the theads that come to early.
Have you tried it?
Does it work
Hi,
I complete pacing schema with 4 iterations :
1st iteration, sum of sampler durations < pacing
2sd iteration, *error *and Thread Group action : " *Start Next Thread Loop*"
3th iteration, sum of sampler durations *>* pacing
4th iteration, sum of sampler durations < pacing

Hi,
When you make load test with load steps, the pacing is useful.
1st step 50% of the load
2sd step 100% of the load
3thd step 150% of the load

The pacing for an iteration is constant and the number of samplers is
proportional to the number of threads

Unfortunately, the images are not yet enabled in this mailing list.
I've filed https://issues.apache.org/jira/browse/INFRA-20125 to fix that.
Could you please upload the image to gist.github.com or something like that
in the mean time?

Hi
a little schema to explain the pacing for an iteration for 1 thread
The waiting time to complete the pacing is a dynamic waiting time.

How do you compute "pacing" then? :)
I guess you almost always have something on the number of scenarios per
hour :)

Hello,
What about following use case:
- You have a number of virtual users running a scenario which is composed
of 30 steps related through correlation of ids
- You set thread group to Start next thread loop on error
- you don’t have a requirement of number of execution per minute
How do you
Hi,
Pacing is used in Neoload, Loadruner...
But I am agree with Vladimir, we can use "Precise Throughput Timer" and
"Constant Throughput Timer"

Can you please clarify how pacing makes it practical?
For instance, I have never faced a case when the
