Hi,

I am a newbie to Gatling world and currently using it for performing load testing on set of REST APIs

I am trying to do load testing using below snippet

_setUp(_  
_jsonFetchCardEndpointScenario.inject(_  
_rampUsersPerSec(0) to 100 during(300 seconds),_  
_constantUsersPerSec(100) during(20 minutes),_  
_rampUsersPerSec(100) to 0 during(300 seconds)_

_)_  
_).maxDuration(35 minutes)_  
_.protocols(jsonHttpProtocol)_  
_.assertions(global.successfulRequests.percent.is(100))_

Every time I run above script for the same scenario, count of request and Request per sec is same irrespective of differences in response time readings. What I am looking for is - changes in code that should be done to have count of request and request per second different depending on response time ?

Please check in scenario, do you have .forever{ or .repeat{. This condition will controls number of requests irrespective of response time and failures.
