Thanks! >>> I've definitely repeatably measured consistent performance penalties for Windows over other OSes on the same hardware

Not sure about the deal here though, I have a really high-grade Macbook Pro at work and it is always, always constantly noisy and heating up with something as simple as compiling a medium-sized Java project.

Whatever any of the fanbois will tell you, no OS or machine is perfect!

I also put a fair amount of time into tuning my build systems to be efficient, which can help with the kind of (very real) problem you mention.

An unexpectedly nice feature of my MBA M1 is no fan noise at any time. I long ago switched all my other machines to fanless, eg so that they could run overnight quietly, but my laptop never making fan noises is good!
