The Jmeter synchronization timer is similar to the loadRunner assembly point and can achieve theoretical concurrency, that is, when a certain number of requests are assembled, they can be sent simultaneously.

1) Add a synchronization timer

Right-click thread group -> Timer -> Synchronizing TimerCopy the code

2) Parameter setting

A. Number of Simulated Users to Group by: Timeout Setting Jmeter has no timeout by default. If it is not set, the system will wait until the accumulated number of requests has not been reached. Method reference (ms) : Number of concurrent threads * 1000 / (number of threads/how many times to start so many threads)Copy the code

3) Scope of timer

Applies to all requests after this timer, that is, the timer takes effect before the request is executedCopy the code
