There is a function in LoadRunner that can set a rendezvous point. As the name implies, it is to set multiple virtual users to wait until a certain point in time, and then send requests together to achieve the purpose of concurrency.
What does assembly point mean?
Block threads until the specified number of threads is reached, and then release them together, which can generate a lot of pressure instantly
Where is the rendezvous function in Jmeter?
The rendezvous function in JMeter is to use the Synchronizing Timer to synchronize the timer function, that is, to simulate multiple users and multiple threads concurrently requesting at the same time
Concrete operation
1. Add Synchronizing Timer synchronization timer
2. Synchronizing Timer synchronous timer parameter description
The number of simulated user groups: that is, the number of concurrency, how many requests are collected and sent together
The timeout is in milliseconds: the number of seconds before the specified number of people gathers is considered a timeout, the default is 0, and it will wait forever. If it is set to 500 milliseconds, if the concurrent number is collected within 500 milliseconds, it will be sent out first.
