Jana Sattainathan checks the labels on these bottles:
A lot of times, you have nearly identical database servers for an application running in Production, Test and Development but you may notice performance differences between them for the same data/queries that you could not attribute to any reason since CPU, Memory, Disk etc., may all be identical.
This is, strictly speaking, a comparison of configurations rather than data differences, indexing, and the like. Nonetheless, it’s useful to make this sort of comparison just to ensure that your instances have your desired state configuration.
