New And Confused

All

I am usinjg soapUI to test a web service. So far so good! Now I want to create a load test so I added a test step and I get presented with an editor that confuses me.

Can anyone tell me what Strategy is? It has four values of Burst, |Simple, Variance & Thread. What is Random? What are the numbers "min", "max", "avg"?

Any explanation of the above is greatly appreciated.

Regards

Patrick
