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.
