> The default load balancing policy in cassandra-stress is null, which means that the driver
will currently wrap {{DCAwareRoundRobinPolicy}} with {{TokenAwarePolicy}}. 
> However, when a white list of nodes or a data center are specified in the command line
options, then either {{WhiteListPolicy}} or {{DCAwareRoundRobinPolicy}} are used respectively,
without wrapping them in a {{TokenAwarePolicy}}.
> This means that in the default case token aware routing is applied, but in some cases
it is not. Token aware routing could give a performance boost of up to 2.5 times on bare metal,
making comparisons of workloads problematic, if it is applied inconsistently.
