How to send concurrent requests in Jmeter

Question

I want to use Jmeter to capture response times for requests to my web script in a concurrent way, but Jmeter sends them sequentially. Is there any way I can simulate concurrent requests?

I'm looking for something similar to web_concurrent_start() in LoadRunner.

Answer 1

JMeter provides Synchronizing Timer which can be used for kicking off all the requests in its scope at exactly the same moment.

See Using the JMeter Synchronizing Timer guide for more information on where to place, how to use and existing limitations.

Answer 2

You can try TailSampler plugin - it simulates browser behavior by retrieving resources in a parallel way.
