The best value for Constant timers in Jmeter
Hi All!
I have researched about Jmeter. I'm a beginner of Jmeter. And now I have a question and hope everyone will help me. My question is: "What is the best value for Constant timers in Jmeter?"
Should I use Constant timers or use Throughput Constant timers?
Thanks you very much.
Best Regards

Hi
Im not sure whether I should interpret value as "what is the use of ?" or
whether you literally mean value.
Lets take your example - Suppose your site does have 5000 users active at
any given point of time - However probably not all of them click something
at exactly the same time - So your concurrent usage may be for e.g. 1000
requests per minute. If you wanted to model this , you could create a
thread group with 5000 threads , but add a constant throughput timer to
ensure that JMeter only makes 1000 requests per minute.
Constant timer as before is to introduce a pause between requests which is
how most users would behave.

Hi man!
Thanks for your supporting, and if I have a test plan with 5000 concurrent users so What is value of constant timer? Or What is value of Throughput Constant Timers.
Best Regards

Hi

There isn't a best value - Timers are used to simulate think times in a test (or introduce delays) and are dependent on what you are trying to do in your test. For e,g, if say a user is presented a registration form , then the user is likely to spend some time filling(larger delay) it v/s say a search results page where the user might simply click the top result (smaller delay). So its upto you and your test As such the constant timer doesn't work for most use cases -since delays are random in nature. Constant timers are sometimes useful in diagnosing race/ deadlock conditions where it is for e.g. necessary that thread 2 start exactly x milliseconds after thread 1
>Should I use Constant timers or use Throughput Constant timers?
Again - depends on what you want to do.
Constant timers - delay a thread for the specified time Constant throughput timer - Maintain the throughput at the specified value (i.e. say you want to accomplish 100 requests per minute).
Note in both cases while the names say "constant" - the value can be changed while the test is running.
I'd suggest you think about what you want your test to do and then match it to how to do that in JMeter rather than the other way around.

There isn't a best value - Timers are used to simulate think times in a

then the user is likely to spend some time filling(larger delay) it v/s say

As such the constant timer doesn't work for most use cases -since delays
are random in nature. Constant timers are sometimes useful in diagnosing
race/ deadlock conditions where it is for e.g. necessary that thread 2
