FF usually runs with interrupt mitigation at higher rates (8-16 or even more packets / interrupt). I agree though that it probably does not make too much difference. alloc_skb could probably be made cheaper for the FF case by being more clever in the slab constructor (I think there was some bitrot during 2.3 on the cache line usage -- 2.2 pretty much only needed 2 cache lines in the header for a FF packet)
