title: DB benchmarking - cluster vs instance?
body: <p>Say I want to benchmark results of a configuration of two databases (index-related to be more exact) and compare their differences. </p>
  
  <p>What would I need to look out for between running the test of either two server instances side by side or a two databses on same cluster? For example, if I had two instances, it wouldn't make sense to have both online at the same time while performing tests since their activity will greatly influence the benchmark result.</p>
