The MoreVRP Variance Graphs compare different data sets, for example from different databases or different time periods, incorporating a variety of analytical tools to pinpoint the similarities and differences and detect the reasons for the discrepancies and their impact on performance. The module enables sophisticated comparative analyses of the data collected in the repository according to a variety of different parameters.

Mining the rich MoreVRP repository, the Variance Graph can rapidly pinpoint problems occurring during  application, OS and DB migrations and updates; the module helps determine the root cause for performance degradations occurring after application or database changes.
