When I have my settings of the script as below

Concurrency : 1 hold-for: 0s ramp-up: 1s throughput: 10 iterations: 100

What does it mean

1 Answer 1


Concurrency and Hold Load For related to the Concurrency Thread Group Plugin.

Ramp-up means is the time JMeter will take to start all concurrent requests: If you setup 100 requests and ramp-up of 10 seconds, JMeter will start 10 requests per second, on average. Throughput is the amount of requests completed by per second, shown e.g. on an Aggregate Report. Iterations is the number of times a Thread Group will be executed. E.g., if the example above of 100 requests have 5 iterations, a total of 500 requests will be sent.

  • I am slightly confused with the different between ramp up and hold for

  • Hold Load For "overrides" iteration. If you determine X seconds to Hold Load, JMeter will continually hit the endpoint for X seconds, no matter how many requests is sent. Ramp-up determines only the cadence of requests in each individual iteration - when an iteration ends, it starts "counting" again. Jun 19, 2019 at 14:35
