Re: Constant Throughput Timer confusion
Hi All,
I have done some analysis with Constant through put timer but it did not
work as per definition/my expectation:
Please see the below chart & let me knowIf it is fine Or Not.
Threads Loops DurationToRun(Sec) ConstantThroughPutTimer(Samples/minute)
Samples Throughput(Request/second) Ideal Throughput should be as per
Constant throughput timer (samples/DurationToRun(Sec))
50 1 60 sec - 50 4.0/sec -
50 1 60 sec 240 50 4.4/sec 4.0/sec
50 1 60 sec 120 50 4.0/sec 2.0/sec
100 1 60 sec - 100 3.8/sec
100 1 60 sec 228 100 3.9/sec 3.8/sec
100 1 60 sec 114 100 3.8/sec 2.4/sec

Constant throughput timer is not working as ecpected.

Thanks. but it did not make clear. Can you define the expected constant
throughput time for my data which is i calculated marked in RED
Threads Loops DurationToRun(Sec) ConstantThroughPutTimer(Samples/minute)
Samples Throughput(Request/second) Ideal Throughput should be as per
Constant throughput timer (samples/DurationToRun(Sec)) 50 1000 1800 sec -

Constant Throughput Timer confusion
Posted by Rajiv Nanduani <ra...@gmail.com>.
Thanks for the input,Again i tried the same as mentioned by you for 30
minutes but still the same thing is happening. I am not sure is the result
is coming wrong or correct. Please let me know Ideal Throughput should be as
per Constant throughput timer (samples/DurationToRun(Sec)) is expecting by
me is correct or not.

There's only a single loop, so it's impossible for the timer to adjust
the throughput.
You need to ensure that the test runs for long enough to allow steady
state to be reached - several minutes as a minimum.
30 mins is more realistic for a meaningful test.
