What it is
The Concurrency Thread Group provides a better simulation of user behaviour because it lets you control the length of your test more easily, and it creates replacement threads in case a thread finishes in the middle of the process. In addition, the Concurrency Thread Group doesn’t create all threads upfront, thus saving on memory.

Example
scenario:
- 10 threads
- 10 minutes Ramp Up Time
- 10 Ramp-Up Steps
- 1 minutes holding the target rate
This means that:
- Every 1 minutes 1 users will be added until we reach 10 users. ( 10 minutes divided by 10 steps equals 1 minutes per step. 10 users divided by 10 steps equals 1 users per step. Totalling - 1 users every 1 minutes).
- After reaching 10 threads all of them will continue running and hitting the server together for 1 minutes
