It would allow to provide a hint to the question "Which lib is the fastest and fulfills the needs in terms of accuracy for the intended use-case?" I agree that the best way to do this requires to run all libs on the same hardware and OS, which is not feasible in your approach. What may be feasible is to compare the relative performance of those subsets, which you run on the same hardware.
