Constant throughput timer

[David Schulberg <Da...@objectconsulting.com.au>]

Hi All,
 
I have a thread group for which I have 10 threads looping 10 times and I have 7 samplers in the thread group. I let the requests run until completion and that takes 2 mins consistently.
 
Now I add a 'Constant Throughput Timer' at the same scope as my samplers to throttle the throughput to 245 requests per minute. I expect the time taken to be just under 3 mins to get through the 700 samples.
 
However I find that the time taken is actually more like 3.5 mins. How come? 
 
 
Regards,
David Schulberg

Remember that Timers are applied to ALL samplers in scope. Make sure
it is not being applied more than once.
