How to interpret various measurements reported in Activity Monitor, from % CPU to Energy Impact, and how they can be compared across different Macs.

macOS Monterey is the first version with support for lightweight virtualisation on Apple silicon. Here are its greatest limitations, which make it look more like a dress rehearsal.
All about memory: different types, Unified Memory, Mach zones and the kernel, and how to manage system memory problems.
How many macOS guests can lightweight virtualisation run at a time, and can it nest them, running a macOS guest in a macOS VM?
This new version of Viable uses HiDPI in Displays to create a crisp scalable virtual display as good as you’ll get from a Retina display. Here’s how.
Although Monterey supports lightweight virtualisation of macOS guests, it has some significant limitations, and doesn’t support GUI Linux. Full details are here.
Is virtualisation on Apple silicon Macs Type 1 or 2? How does it handle sensitive instructions, exceptions, CPU cores, and manage memory?
Snaps a VM window to its display resolution, offers a fourth display size option, and more errors should be handled without the app crashing itself.
Code run in a guest macOS may perform differently to that run on the host, and will reduce energy efficiency and battery endurance/
Why would Apple invest several years of hardware and software engineering just to see what 3rd party developers might do with it?
