Figuring out why Debian is performing badly and eating battery

Looking at top, on startup there was a bit too much irq/172-iwlwifi but that seemed to go away.

OK the main problem

kworker/0:0H-events_highpri

OK and way too many Isolated Web Co yes i’m working on closing Firefox tabs.

But gnome-shell at the top and all that’s running is top and this nvim window i’m typing in, bah.

sudo apt install linux-tools-generic

Then:

sudo perf

Per https://askubuntu.com/questions/33640/kworker-what-is-it-and-why-is-it-hogging-so-much-cpu
