31-Concurrency Thread Group

Concurrency Thread Group is an alternate to Stepping Thread Group.
This thread group will help us to maintain the concurrency. It won't create all the threads upfront, so it won't use extra memory.
It will help us to check how much load the server can bear for a given period of time.

Why we use the concurrency thread group and ultimate thread group

Can you plz explain how to analyze report here. For 10 users What is the sample -1160 means and How I calculate or understand the responsive time here?

[@nagendrakumar1387]

50 concurrent users
2 calls per minute for each user (translating to 120 calls per hour per user)
Total of 6000 transactions per hour (120 x 50)
above is my usecase
Can you please explain how to achieve this usecase in Jmeter

How to connect a proxy or proxy list to each thread?

[@anissabrina9977]

Hi sir, I want to design an API load test (REST API) using JMeter. This is example scenario:
For the first test run, we want to run 1000 virtual users, ramp-up 30 mins, hold target rate time (sustain load 1k users) for 1 hour, and lastly ramp-down 30 mins.
How do I apply this design test? I'm pretty confused whether to use Concurrency Thread Group or Ultimate Thread Group because Concurrency Thread group don't have the Step Down feature.

Hi Anis, I would suggest to go with for ultimate thread group for this scenario.

Hi Phani, thanks for explaining about Concurrency Thread Group.. can you please explain, why it is executing that many samples? On what calculation the samples are getting executed.
