Delay Between Http Requests

[Nayak, Soumya R.]

Hi All,

Can you please let me know like what is the best way to put delay between HTTP requests.
In bean shell sampler pre processor I had used "Thread.sleep(millis) " , what I observed was if I run using one user and after coming of the response it sleeps for the specified time and then sends.

Is there anything where we can send requests exactly at the specified time without considering the response time of the previous requests.

For example : I submitted a HTTP request with one user at 1:00:00 PM and the response came at 1:00:50 PM , now my thread will sleep (let say delay of 60 seconds) and fire another http request at 1:01:50 Pm but my requirement is to fire the request at exactly 1:01:00 PM rather than considering the 50 seconds of response time.

Is there any way of achieving this?
Also please let me know if in JMeter its possible to submit requests asynchronously?

Regards,
Soumya

Would a Constant Throughput Timer

work for you?

Best regards

if i may ask, why is there such a requirement? it might lead to unnecessary
queuing at the server leading to an exponential increase in response time

You could also use the JSR223 timer to read the current time and determine
how much delay to return. You do however need to figure out what you want
to do when your previous sampler takes more than (in your example) 1 minute
since the window has already passed.

Also please let me know if in JMeter its possible to submit requests asynchronously?

Only if you are willing to code it yourself in for e.g. a java sampler -
The default HTTP requests do not have this feature.
See this for some other options -

You must be looking for implementation of dynamic pacing
