Constant Throughput Timer Concerns

prateekgommt
Hi,

If we are using Constant Throughput Timer with basic Thread group  (
Threads, Ramp up Time & loop) to achieve concurrency of 17K rpm then --


1. In Thread group, do we have to pass ~ 20K threads i.e. Value input for
Threads should always be greater than value defined in Throughput to
achieve ?


2. For *Calculate Throughput based on* field in Constant Throughput Timer,
is it better to select option* 'this thread only'  *compared to *' all
active threads in current thread group'*  to achieve maximum expected
Throughput.


3.Which is best to use among Throughput Shaping Timer / Constant Throughput
Timer / Precise Throughput Timer ?

Re: Constant Throughput Timer Concerns

Ivan Rancati-3
hi,
a couple of ideas

1. It really depends on how long you anticipate a request will take. If you
want 17k request per minute and each request takes 10 seconds (so 6
requests in a minute), start with approximately 17k/6 threads and take it
from there.

2. In general, I think it's better to use slightly more threads and use a
Throughput Timer to limit the throughput. Perhaps it's easier to start with
the Constant Throughput timer.


best,
Ivan
