A variable number of VUs execute as many iterations as possible for a specified amount of time. This executor is equivalent to the global stages option.
In addition to the common configuration options this executor also adds the following options:
|stages*||array||Array of objects that specify the target number of VUs to ramp up or down to.|||
|startVUs||integer||Number of VUs to run at test start.||1|
|gracefulRampDown||string||Time to wait for an already started iteration to finish before stopping it during a ramp down.||"30s"|
This executor is a good fit if you need VUs to ramp up or down during specific periods of time.
In this example, we'll run a two-stage test, ramping up from 0 to 100 VUs for 5 seconds, and down to 0 VUs over 5 seconds.
Note the setting of gracefulRampDown to 0 seconds, which could cause some iterations to be interrupted during the ramp down stage.
