How do you disentangle the performance effects of load generation from the target system? It looks at first glance to all be colocated in the same cluster.

The load-gen and the service does not need to be co-located in case of REST (drill) and PostgreSQL (pgbench) based load testing. In case of pure network benchmarking (with iperf & qperf) currently only the same cluster is supported.
