maybe my linux had a big or wrong setup u know, but it was running very lean. Freebsd runs about as lean tho.
cannot be bothered ofc to go back and measure it is some hp-elitebook withh a ryzen and iGPU in there.
If i run things like Claude it sucks my battery. But if i just run my editors code all day myself its all gd..use firefox as browser on both. other then that its x,i3,hx,rg,fd,fzf. thats about all i use..(so u see i hate it when any laptop empties soon.... i hardly use anything of it). usually i dont even open x/i3.
