Gatling DSL components are immutable ActionBuilder (s) that have to be chained altogether and are only built once on startup. For specific operations, responseTimeInMillis and latencyInMillis are provided by Gatling – responseTimeInMillis includes the time is takes to fully send the request and fully receive the response (from the test host).
