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
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.
