Tigger 10 k user's at once with JMeter

kumar srujan
Hi Team,

We are using JMeter to test an API service with 10K user's for 1 iteration.
We are not using any timers/controllers/ramp up nor any delay time's for
execution.
Test completes in 30 secs.
Now my requirement is to send all 10K requests at once, i.e in one or two
seconds.
Is there any such option in jmeter.

I have used synchronize timer but not that efficient.
Any pointers on this would be greatly appreciated.

Regards,
Srujan Kumar

We can go for different Thread groups too apart from basic Thread Group to
have the expected concurrent users like concurrent thread group.

Thanks ,

Kishore PS
If you are using sufficient load generators, you can get this ramped up in
1-2 seconds

Hi Prateek,

What you mean by different thread groups.
You mean to say "add same request in different thread groups and divide the
users equally in those groups".

Re: Tigger 10 k user's at once with JMeter

Prateek Dua
No, I meant this .Google this and you'll find search results of different
types of Thread Thread group jmeter gives-- available via jmeter plugin

If that not sorts out then give values of  ramp up time and Threads in old
and  basic Thread grp in a way that you meet ur expected requests criteria.

Re: Tigger 10 k user's at once with JMeter

kumar srujan
Thanks Prateek for inputs.
My scenario is that where I don't require any ramp up or steady state for
test. Link provides various types of thread groups and controllers.

After clicking on run button all 10K user's should hit the service in 2 or
3 secs.

Thanks.

Re: Tigger 10 k user's at once with JMeter

Prateek Dua
Hi Kumar,

1. You can refer below links for quick help to set your values to receive
expected concurrency + screengrab  https://imgur.com/a/y4sSWjV  of how
multiple thread groups visible in jmeter by using jmeter plugin.

https://jmeter-plugins.org/wiki/ConcurrencyThreadGroup/

https://medium.com/@kalyani1729mittapalli/load-testing-using-concurrency-thread-group-in-apache-jmeter-63388ac3ec17

https://www.redline13.com/blog/2018/05/guide-jmeter-thread-groups/


2 Also you can try & check this set up --  Ramp up time ( 0.0003 sec) i.e.
[ 3 sec /10000] with Thread grp of 10K users using default Thread group of
to get the expected concurrency. Also the application under Load (  server
receiving hits) can give you correct stats about the hits received per
second fired via Jmeter.

Thanks,
Prateek

Re: Tigger 10 k user's at once with JMeter

Scott Dean
Greetings!

It sounds to me like this might be a case for using the Synchronizing Timer
component.  This will pause the threads until you get to the
threshold (10000 in this case) then release them all at about the same
time.  Insert a flow control action with the Synchronizing Timer under it,
right before the API call you are testing.  Set the grouping to 10000 and
the timeout to something longer than your ramp-up time.  You could leave
the timeout at 0 but if something happens and you don't get to 10000
threads, your test will never exit and you will have to kill it.  Better to
set a timeout that is long enough that you should never get there so the
test will run to completion

Re: Tigger 10 k user's at once with JMeter

glinius@live.com
In reply to this post by kumar srujan
If you have a Thread Group with 10k virtual users, no ramp-up, no timers so
JMeter is running at full speed and you have 10k requests executed in 30
seconds I can think of 2 reasons for this:

 1. Your application cannot respond fast enough which means you found the
bottleneck <https://www.quora.com/What-is-bottleneck-in-performance-testing>
, there is no sense to continue until the bottleneck is identified and fixed
 2. JMeter cannot send requests fast enough. Make sure to follow  JMeter
Best Practices <https://jmeter.apache.org/usermanual/best-practices.html>  
and if you will be limited only by your machine hardware specifications you
will need to consider going for  Distributed Testing
<https://www.blazemeter.com/blog/how-to-perform-distributed-testing-in-jmeter/>
