Absolutely, I agree is not something to *worry* but I think it makes sense to investigate as the possible fix may be trivial. Part of the reason I wanted to recompute them was because the micro-benchmarks published in the What's new of 3.9 were confusing a lot of users that were thinking if 3.9 was slower.
