Part of the LoadGen testing is the initialization of your database(s). My understanding is that this increases the size of the dbs to actual size. If Icurrently have only a limited amount of storage available is there any other way to simulate concurrent connections and mailflow to validate at least server performace on the processor and memory end. Thanks!
