How to understand My graph results
Hi,
I have ceated my test plan as shown below
T(50)
R(10)
Loops(3600)
HTTP Sampler
I am getting graph results as
Average latency is 1985ms , Throughput as 22.9/sec ..
My understanding is
we loading the server with Threads per second(users)(50/10=5) i.e. TPS =5 ,
so at max the server has to show me max throughput it is handling as 5tps,
since we are htting 5tps and if server is handling all requests successfully
then throughput has to be 5/sec. How come throughput is 22.9
i have gone through
http://jakarta.apache.org/jmeter/usermanual/test_plan.html ...
can anyone please interpret these results for me, where i am missing...
Thanks in advance...

Think about how JMeter runs each thread.
JMeter runs the sampler.
The sampler makes the request, and gets the response.
JMeter processes the next element in the test plan, which in this case
is the sampler again (as there are no timers).
So what determines when the server sees the next sample?

Thanks sebbaz,
One more doubt ,If rampup perriod is nothing to do with TPS then how
do i calculate my Load
i.e. How much is the Load(threads per sec) at which i am hitting my
server...with the following plan...
My understanding is 50 users(threads) accessing server
simultaneosly...meaning 50TPS...am i correct..
Please clarify

No, the ramp-up has little or no bearing on the TPS, except possibly
for the first iteration.
It only controls how long JMeter takes to start all the threads, after
that they are on their own.

Throughput is calculated as requests/elapsed time.
