This time the DELAY env variable is injected as a Long value, with the following syntax (dont forget the .toLong statement at the end, used to convert a Java Long into a Scala Long value): Using a Long is mandatory because the .customPauses(session => delay) DSL component requires a Long value: It takes a function in parameter, with the following signature: (session: Long) => Long. Gatling is fantastic tool when you just want to load/stress test your system without worrying much about other performance requirements. "Typically" implies there are cases in which they can be used.
