test log for set throughput as 150000

test jmx file contains elements as below:
Testplan
  -- Thread Group
     -- Debug Sample
     -- Constant Throughput Timer


Testing....
set thread num: 2000
set Target throughput: 24000(400 QPS)
<all active threads> mode
result: about 410 QPS

<all active threads(shared)> mode
result: about 333 QPS

======================
set thread num: 2000
set Target throughput: 45000(750 QPS)
<all active threads> mode
result: about 765 QPS

<all active threads(shared)> mode
result: about 1000 QPS

======================
set thread num: 2000
set Target throughput: 150000(2500 QPS)
<all active threads> mode
result: about 2511 QPS

<all active threads(shared)> mode
result: about 392,199 QPS

no matter what type request, result QPS always 333 when setting Target
throughput as 24000, result QPS always 1000 when setting Target throughput as
45000, result QPS always can't control when setting Target throughput as
150000.

Hello,
This component is only  able to reach throughput for a test that last enough
time, your test lasts 2 minutes, it's not enough.
Also you need to ensure you have enough threads to reach target throughput.

In both case, it is better to ask on jmeter user mailing list before opening a
bug.

So I am closing as Invalid for now.
Feel free to reopen with more details and sample test plan.

Thank you
