How do I interpret ByteMARK / nbench results?

Question

As part of a server burn-in process, I am running nbench (BYTEmark). The results show two FLOATING-POINT Indexes and two INTEGER Indexes in the results, one under "Original Bytemark" and the other under "Linux data below". Which is the "real" score?

Where are the results with some lines removed for brevity:

Answer 1

Both scores are "real", but they're relative to different systems. The "Baseline" listed after each set of results lists the characteristics of the system that the speed is relative to. The second set is probably more useful as it relates to a more modern setup.
