This is somewhat the same using the "system information view".
Although technically not incorrect since it shows "MB per measurement interval" and not "MB per second" (as pointed out with the red arrows) it looks weird.
The red boxes show the part when it is set to 1s interval, the blue box shows when it is set to 5s interval.
This is displaying disk and IO when starting with 5s interval:
And then I switch from 5s interval to 1s interval:
Reminds me of the CPU% changing when you look at same program on machines with different #'s of cores.
Problem is that with more cores, more processes show no cpu usage (you can see an indicator if you turn on option to see processes using less than .01%), but that doesn't tell you much and looks noisy. *sigh*
