Cluster configuration
Two clusters were used for the test because some of the machines were re-purposed during a break in testing. However the test clusters were essentially the same, different virtual machines of the same spec were used.
Cluster 1 was used for the 3 and 5 level expanded vs unexpanded testing. Cluster 2 was used for additional tests using 3 levels and varying numbers of VariableInstances. This table describes cluster 1 with cluster 2 details included in parentheses where it was different.
