What is Ramp Up Time in Load Testing

The Ramp Up Time property represents the delay between start of the test until all virtual users are running.

This is independent of the Duration setting and tells how long to take to "ramp-up" to the full number of Virtual Users chosen.

Ramp Up Time needs to be long enough to avoid too large a work-load at the start of a test, and short enough that the last virtual users start running before the first ones finish (unless one wants that to happen).

This setting is similar also for JMeter Load Testing.
