I'm on a dual screen with 4k and 2.7k (Surface pro 4) intel graphical chipset, i7 with 4 cores.
On a 20.04, using gnome-shell over Xorg, gnome-shell proc usage jumps from 0-3% to 40-60% usage when using indicator-multiload.
gnome-shell over Wayland will have same issue, with an added visible mouse stuttering problem.
interestingly, I've installed unity7 (with ubuntu-unity-desktop 0.2), and this doesn't occur on unity as dramatically: it goes from 2-4% without indicator-multiload to 6-8%. This makes it totally usable on unity.
