Some people think it is ridiculous to measure the power consumption of computers.

Imho it is important for servers but also if workstation uses 50 Watts idle or 10 can also make a difference when it is used a lot over the year – for the envinronment and the electricity bill – one always wants maximum performance per Wattage.

watch cpu usage via htop (linux task manager, apt install htop) going through the roof.

variant dev null:

no screen output.

yes > /dev/null & # stress one cpu threads/cores
