Create multiple virtual LoadGenerator machine instances.
Having multiple virtualized LoadGenerators on a host machine is better than having a single virtual LoadGenerator machine because the hypervisor of a virtual platform scheduler works better when there is a diverse workload than when there is a homogeneous workload. Remember that virtualization software like VMware – be it whether it is a ‘Type-1’ or ‘Type-2’ hypervisor — it is designed to support as many virtual instances as possible on a single physical machine. A simple illustration: Load generator working on single virtual machine emulating 100 Vusers is likely to use more CPU resource than when the same 100 Vusers are split across into 2 virtual machines – 2 load generators.
