I seriously doubt the same is true for the IO requests (which are different anyway, and tend to happen at a much lower frequency than high-speed networking).
I also suspect that your timings were very hardware-dependent in the first place (and yes, the long-term effect is likely working against that "optimization"), and depend a lot on just how sparse the initialization can to be.
